Data Type and Variable in C

For example, if you take any variable, then where are you storing all the value in the variable? Where are you storing all the value in the variable? If you want to store it in a variable, then when you store it in the variable, then you will also have to tell what is in this variable. What is the value you are putting? Understand the thing. The value you are putting in that variable, whether it is a number, a word, a sentence, a date, how is it, you will have to tell it, only then the computer

will work properly. Whatever term we use to describe this thing, the name of that term is data type, so what does data type basically do, what does it tell the computer , what does data type tell the computer, how is the thing we use stored? Yes data type basically tells what kind of value we are going to store in the variable we are taking. He does not understand the value by looking at it. Give an empty value, write A B C D. Think that the computer understands. Take it, whatever it is, whether

it is a number, a word, a date, this thing does not happen with a computer, okay, so it says not to us, we don't remember, what was told in the previous program about ABC, CD, we don't remember now the new program. You are writing this, tell us, have you understood? Yes sir, what will you need in every program? So in every program you will need a variable. Okay, to store it, when you take a variable, then with the variable. What you should know: Data Type: Every variable will have its own data

type so that the computer will know that whatever is being stored in this variable is of this type, it means whether it is a number or a date. It is a word, a sentence , and whenever you use that variable or do some calculation in it, based on its data type, the computer will understand whether it is a number, a word, or a sentence and will calculate it based on that. Okay, so you have understood one thing that if you want to store anything, you need a variable and whenever you declare a variabl

e, you will tell the computer that it is a variable, then you will also have to tell what kind of data you are going to store in this variable. If you don't tell me then the computer will not understand what it is, what is going to go in it, how it will be used, it will not understand anything, have you understood the thing or is there any problem in understanding it? Yes sir, it is fine, so now if we come to the different balls . That brother, sorry about the data type, which data type is there

, there are a lot of data types, okay, there are a lot of data types in the computer, but mainly, if you are in C language, okay, main. Generally, if you are in C , then your 'y' will be numeric, it is ok and the second one will be 'w', this score is ok for the character, how did it become numeric and 'care', 'care' means short form, is there any problem in understanding this, no sir. Now see what is happening here that if yours is numeric then there is no word like numeric in C language in your

computer or there is no name of any type like numeric, okay to tell numeric, to tell that brother it is numeric. So, so many data types have been given to represent numeric values ​​in the computer. Whatever we write here is P int i nt int int, which is the short form of integer. Do you understand that you have studied mathematics ? What is called 'Inger'? Yes sirko bole hai numeric value numeric value kaisa numeric value kaisa numeric value whole number or falling point number or floating poin

t [music] wala sorry kaise numeric value ko integer bole hai e number wa to or 47 yahi sab yes meaning hole number is this l Pat Nahi Te Rat Number F Number Yes Sir Hai Na Yes Sir Ya Bhi We have already told you that we have already told you how the computer language that has been created has been created so a word like English has been used so that People do not face any problem in remembering, reading and understanding, that is why there is a data type like 'P', its name is 'In', meaning what

kind of value will go in it, 'Int' is its short form, 'Int', understand the thing, yes sir and What is int in int, how much space will it take in the memory, four bytes are read by bit byte, ba ba, you have told in cup fundamentals, it takes four bytes of space in int, what does it mean, how much is stored, how many bits are there in it, what does it mean? Now I will be first, what kind of number will go in 't', full number, right hole number, second, hole number will go in ' inger ', second, ho

w much memory will be given at that place. If you store a variable of int data type, then it will take four bytes of space in the memory. Meaning, it will take 32 bits of space, have you understood, no problem, yes sir, and if you take a variable of int type, then the minimum value that you can put in it can be this much and the maximum that you can put in it is from negative to this much. If you understand the matter till positive, then if you want a bubble which has this much value, this much

from maximum and this much from minimum, this much from negative and this much from maximum, if your work is going to be done then you will use it, no problem, hello yes sir. No problem sir, no sir, there is another data type, that too is for numeric only and that data type is named sort. What is the name of sort sort? Neither will it consume two bytes of memory. How much will it spend? Two bytes two. Byte memory and that too is only for storing numbers but what will be its range from minus 3276

8 to 3276. Have you understood the thing? Yes, after that you have Ya Lang, what is Lang, it is of four bytes, Ya Lang is what it is, right? It can be of four bytes or it can be of more bytes, okay, if your computer is 32 bit, no computer is of 3 bits, whatever computer comes and is of 64 bit, okay, if it is 64 bit. If you have a computer, then whatever is yours, it will take 8 bytes and when it takes 8 bytes, its range, you can see from where to where, it is quite big. Okay, yes sir, after that

, if you take float, what will you take? There is another data type name. In this you will have to remember the name of the data type, what has become int, shrt, long, float, okay if you take float, okay if you take float, this also takes four bytes of space but in this you can also put the fruit value. You can write the meaning of fractional value after the decimal point like 1.5 1.79 1.82 35 50 paise then 3550 If you have to do something like this then what data type will you take, if you want

float then what will you do if you want floating point if this So , your decimal point will also come in the float. Okay, now after that, another data type is given like any float, you can also put a function value in it but it will take up a byte space. If double is a data type, if you Take a variable of double. If you take a variable then it will cost you 8 memory. Are you understanding the thing? Yes and in that you have un sci eight kya hai a hai unsa e unsinde e what does it mean that see

one so you did it . Is it right? Yes sir, it is ok. Look carefully at what is meant by unsigned. Like when we have entered here, here P has both negative and positive values. If you want to tell then you have to give the sign of minus or you will understand without giving it. We understand that sir, give us the address. Sir, we have to write plus in plus. No sir, do you understand what it means to tell you the sign for positive number. But if you have to tell the negative number, then you know h

ow to give the sign, that is, if you do not give the sign of negative minus, then how will the person understand or understand the positive number, or sometimes you may have such a need, is there any way to get the ticket? I wanted to tell how much is the weight. Tell me one thing. Will weight ever be negative? No sir, no sir, you need such a data type in which you can store negative. No sir, sir, that's why you have been given such a data type, but it is unsigned, it means it has negative value

. You will not be able to put whatever will remain blank in it, it will remain positive meaning you cannot give sign, you cannot give sign, what is the meaning of positive le pot sign, you have to give it in negative number, you do not have to give sign in positive number, no sir right, you have to sign in positive number. You don't have to give it only in negative, you have to give it right, that's why it has been named un sign int, double, it is written, it is written, and shirt is written, po

w, so if when shirt is written, then what is its range and what is it also? Positive is also right, in the same way as int has signed int, sorry unsigned int and normal int, in normal both negative and positive will go unsigned, it means you cannot give negative value in it, only and only in it, what you We will put positive value, we will put right, similarly here you have unsigned sort, what will be the meaning of unsigned sort, how much space will it take, how much is taken in the shut, only

two bytes are left but the difference will be that in this, the lake is positive from negative and what will happen in this is only type. Sir, this will also take only double bytes, now this will take only positive numbers, hence its range will increase from what it is to G and your ya will double it. Let us double 65000, how much will it be ? 65 and this will be 5 65 500 and both add 35. Okay, so if you take a variable of data type of 'in', then you can take minimum and maximum values ​​in it.

If ever it happens that you have one such Do you want to take Weble or Jism, you have to put maximum 6000 and put positive, it is okay, you have to put maximum 6 and put positive only, right, then what can you take on this account, so what will be the benefit of doing this, we are int. What will be the benefit or loss at this place? Benefit will be positive value. Only positive and negative and positive are both in PTV. What is this? If there is a restriction, then native cannot do it. Secondly,

what is your maximum? 6535 is fine, the main advantage is that your unsigned string will take two bytes and int will take how much byte, double the memory will be spent, write int so much that the data type given to you is so much in numeric only. The only and only reason for what has been given to you is that what we want is that we want to save our memory, we want to make good use of the memory. If you have understood, then if you want to use the memory properly. If you do not want to spend t

oo much memory unnecessarily, then considering how much memory is spent on which data type and what is your usage, like you have to book a railway ticket, how much ticket can you book at a time? The passenger of the passenger can make a ticket, he can't do more than that, he sees, he makes a ticket for a person in a bus, it is just fine and the firm remains okay, it is okay for a person, let's assume that you book in my show, in book my show. If you go to buy a movie ticket, whose movie ticket w

ill we buy in Bengaluru? Now let's assume that a person buys two tickets, two tickets, four tickets, five tickets, 10 tickets, not just this much, 20 tickets, 50 tickets, 50 tickets, let's assume one ticket is 00. Is the price or 00 is the price 50 tickets 000 okay or if we assume that right now the ticket price also has to be shown on this ticket price or the ticket price will show the ticket price somewhere else ps sir to show the ticket price It would need a Veble. Yes Sir, to show the power

of Sir, let us assume that the ticket price will be maximum which is 500-700 thousand, it depends on the cinema hall, cinema hall and anytime the ticket will be negative, low sir sir, it will not be there and so much. Also sir, will the amount ever be more than 65000? No sir, what does it mean? We want to keep it, can it work? No sir, yes sir, can it work? No sir, can it work? Yes sir, if we take it, it will cost two bytes of memory and if we take it, it will cost us four. Byte Memory Sir, if ou

r work is running with two bytes, then you will do the work with two bytes only. Don't spend variable byte memory. Memory is very expensive. Yes, and what is more important than being expensive, what is your rum, tell me, it is limited. Isn't the storage capacity its head? What is the storage capacity of the rum? It is limited. It is most important. So, the more you save it, the more programs will run. Otherwise, if you spend all the memory in one program, then only the program will run. A few m

ore kilos will be added, so when you make software, you make it all with the thought that the less you spend, the better, this is what we have learned, don't you spend all the money you have, save it and spend it instead of doing work. It can be done and the work can be done with the shortage. Sir, what money does everyone have? It is limited, that is why we want this. Where there is some limitation, we want that my work should be done in minimum amount, this is not right . Why do you need more

memory in your program? If the work is going on, then use the less one, the work should be done with less, that is why all the things you are seeing are numeric, but there are so many types of types for numeric. What is its region given? You see, we have given you all the options, in two bytes, in four bytes, in non-cye, with decel point, with decel point, we have given you all the types, type the data as per your requirement so that You will be able to use the computer's resources and memory fo

r processing in the best way. Okay, now let's assume that one is the subtraction and multiplication division of a whole number, which is the whole number and the fruit number and the other one which is the subtraction and multiplication division floating. A of point number, tell me one thing, in floating point number it takes more effort, in the case of jota times division, in the case of whole number, it takes more effort, in the case of whole number, you have to work less in floating point. Mo

re should be done, even if it is of the same type but the method of calculation in int will be less or more or less. So if you never want a fitting point then what should be the data type? What is the main purpose of Gaya Name? What is Main M? Why is it given so that you can use both your memory and processing properly? So what we were saying is that if your int is a whole number, then the whole number is also four bytes. Int will also take four bytes and float will also take four bytes. Both wi

ll take the same amount of memory but the processing will be more in which type. In this case, the processing will take more time. In the case of float, it will take more time, at the place where your whole number can be used. Full Whole number works fine, there you take int, but where you need to take decimal point, what will you take, float, ok, I have understood the point, in the same way, double is yours, 8 bytes and one more is given to you. What is lung double given? Okay, this will take y

ou 10 times or more based on computer. 10 times its range will be very high and in this also you can use clotting point. Okay , so all these things are for you. Pass, this is your data type related to int or int jar. int int jar shirt long float double long double hai na unsigned in unsigned short, similarly you have this in long also na long kaun gaya lang likhe hai na lang at white long me You also have unsigned long. What is unsigned long long? So what will be the difference between long and

unsigned long? It will remain long without sign, it will take the value yes, it will take positive value and its range which is negative, if it is not there then the same thing with negative is positive. Meaning, what will be the value, will it be doubled, how will you see, as it happened in this shirt, the maximum was 32000, when the unsigned shirt was made, till where it became 6000 000, so basically what happened is the minus one, which is there, was added here right. By mixing both of them,

from zero to 65000, in the same way, what will be the unsigned line, whatever is negative will be added to the positive, the range of positive will be increased. Have you understood? Yes sir, if A takes a byte then it will be unsigned. Will also take a byte and this thing, you all should remember, this will be very useful, you should know one more thing, today we are telling you and you have to remember this whole life because this thing is empty language. It is not like you are studying in Java

, later you will do anything. Those who want to do full stack development, those who want to go into software development, those people will not be able to use simple C. This is your basic primary language for starting. Which is also in the syllabus of all your people, but when you do full development, then whatever is the job for you in development, what is the meaning of character character in word word, what is given here that a data type is given and its name is given . Gaya Ka read this as

K means the short form of the character is correct and what happens in this care, you can take one character, how much can you put, if you take a variable like one character, then you can put one empty character in it, like A will be empty, A will be B. If you want to write Apple, then you will have to tell there how many characters you want, we will talk about it when we come to programming, okay but for now, just know what data type is there and how much can you put in it. Only one conductor i

s ok and how much memory will it consume per byte. Now you will also write ABCD, that too what will be stored in the computer, how will it be in the format of S in binary, 0 and K in binary, then say ABC CD. How will we write 'K' into 'zero one'? No, if we write 'a' then how many zeros and 'ones' will we write after that, then what is whatever character you have, whatever character you see in the keyboard, A B C D Tooth F, apart from that, Usum Xm Mark Rate Dollar. Percentage is but the lesson i

s greater than equal to 1 point comma full stop. Whatever you have seen in the keyboard, for every key, every key has a character, one, two, three, four and there are also characters. Understand the thing, you see as many things as your key, all are one. There is a conductor and every conductor has been given a number for each conductor. What has been given for each conductor, a number has been given and who has given this number, who said that brother, whatever number of conductors are there in

your board, he has been given a number. If you want to represent in I, then who is the name of the organization providing this? It is ASCII Standard Code for Information Interchange. It is okay that a coding format has been given to you. It is okay that the coding format has been given. The meaning of coding format is every There will be a numeric value of the character, it is told that yes sir, say okay, tell every character, please tell us what is its value, then its value is like this, when

you write A, the computer understands it as 65 A, what will it understand as 65 B? 66 C is 67 and okay sir yes sir, in the same way A is 65 B is 66 C is 67 6869 A7. By doing this, we will reach the root and where will we reach. 90 is a continuous value till 90. It is 26 letters, right, if you look at it from 6. 26 letters are 65, 26 is 26 Sir, 65 will also be played, yes sir, 26, 26, remember this for every character, we are going to use this in the program now, we have to remember a lot of, oka

y, so what happens now, if you write A, it will be 65. But what will be stored in the computer, it will be stored in the computer, it will first convert 65 into binary in the format of G and whatever comes to G, it will be stored in the computer . Have you understood the thing, it is converted into a number and the number is then converted. What happened to binary and what happened to binary number? Well, whatever character is given here is no. Whatever character is given in your keyboard, all t

he characters are there, from zero to 255, how many characters are there, from G to It is okay till 255. Whatever is there till 255 is in your butt. Write 255. When you people were showing the binary number then it was 25. If you are in the mind then you were made to do Ba and L. Yes sir. We deliberately got the decimal fraction of 127 and 255 done. If you guys care, then why did it get done? It is okay. We told the reason why it was done. There was some reason for getting it done. Okay, if you

see, then I said that you are doing decimal decimal. Demal was in Riba, got 127 done when he did kitna ka ka kitna bar a aayega ya sab me aaga ya minus jo hana woh different ya se le ke sa digit aaye see if you do it in eight then how much aaya aaye yes sir ok If in aat, how much will come, ok and in sa, how much will come, ok, understand the thing, yes sir, now what is the problem here, 8 bytes will be used to store one character, how much sorry, 8 bits will be stored in one byte. Okay, you hav

e been given the maximum amount to store one character to store the value, neither byte nor byte, 8 bits, nor byte, there is zero in it, either you write from zero to 255 or from minus 127 to 127. Yes, if you understand, then subtract it. What will be the meaning of then how much is yours in seven characters? It is up to 127. Yes sir yes sir 27 ho ki na ek doti cha pa 6 sa saat hai ji sir who converted 127 into binary seven is one yes sir so By combining seven characters, you can write from zero

to 127. 127 is the highest number. If we ask about seven digits then what will you tell? What does it mean in binary number? If you have to tell the largest number among seven digits then what will you tell? All yes. Sir, if you tell me the largest three digit number in the decimal number system, then what will you say? 9, sir will you say? If you tell me the largest three digit number in the decimal number system, what will you say? 999, and if you say the smallest, then you will say yes, sir

right. In the same way, in binary number system, why tell the number here because here you use from where to where, zero to no, no, yes sir, what will be the biggest number, will the last one 999 be bigger than no? I will say, tell me the biggest number in three digits, what should I tell in Banari [Music] Yes Sir Saras Sir, in the same way, what will be the biggest number of your saat, what will be the biggest number in Banari, which is yes sir, okay, now what does it do with seven digits? I ha

ve made it zero. Yes sir, what will be the smallest number? Byen G will become zero. One character which is your 8 bit or one byte gives space, then if you see the maximum number of characters you can put in 8 bits, how much will you take from zero to 255? Will you be able to put 255 256? How many characters can you put in total by using one byte? 255 255 Brother, add zero also and it will become 256. Yes sir, yes, that too is a number, that is also a value, right? Yes sir , right, the total is

one byte, you can enter only and only 256 characters. Okay, yes sir, there are two things here, one is that you use all eight bytes and leave the positive number empty, then what will happen to you with zero. Take 255 and the second thing will be that to give number for the number, use seven, then what will be your maximum. In 157 plus, yes sir and this is one character in the beginning, either write one in it. Understand the meaning of one is positive and write zero. So understand its meaning,

negative negative happened, yes sir, if you write zero in the beginning then it will be understood as negative. There is a value and if you write one at the beginning, then it is a positive value. Now understand that the remaining 127 will be there from here to y, hence the meaning is mine is from 127 to 127, which means how much is being used in it. Basically, bit is being used. How much is it but for your value that you want to give and a bit and keeps reserve for what sign for sign for unders

tand the thing yes yes sir what is the result of that a b joey reserves for sign Its result becomes that what does your range become, how much does it become half straight, half zero means in a way, if seen in positive, then what became straight, instead of 255, how much is the maximum 1277, I understand . I understood the difference between beat and a bit. Yes sir, the same thing is yours here, which you see like int, see shirt wala, what is the range in shirt, bytes means 16 bits, byte means h

ow much 16 bits but right and Where is the value from where to where is the value 32 767 so how many bits is it using? 15 bits and what is one bit for? Understand the point for sign. If the same thing is unsigned, what will we do to unsign unsigned, meaning it is 16 bits out of 16. Will you use B range, how far will it go, double it, double it, 65 65, have you understood? Yes sir, whatever ridge you see, no, whatever ridge you see, everything is the power point of binary numbers. Okay, understan

d. By getting number 16, you have got so much. The value will be from zero to 635. If you do not know, we will show you, then many of your websites are made. Convert Binary Decimal Online. Ok and now what do we do here? We say binary number, give 15 digits, 3 Ch. Pa 6 sa 8 9 10 11 12 13 14 15 15 hai na doti 4 Pa ​​6 sa 8 9 10 11 12 13 14 15 hai convert it into decimal how much did it cost 32767 ok let's do one more k how much did it come understood. Yes Sir, if you understand, if you have to wri

te in I, then how much will it come in but, what will happen in B, okay, if you know how to write demal, then you have to write in pa digit, and if you have ta, then understand the thing in 16 digits. Yes sir, now you have understood that. From where is the range defined and because we are using binary numbers, how much memory is required, so if you want to know 8 byte car, what do you need to know, 8 bytes by bytes, you can understand 44 one. Right yes 64 bit yes sir I understood that you have

to know the value of 64 bit but there is a difference in this, what happens in value is that you only give the whole number so this is the number, okay understand the thing and what will be in the float, you can also give the function point. If given, its value and range will be slightly different. There is a byte in double, but it also has floating point, so its range will be slightly different. Long double in double will take 10 bytes, meaning 80 8. Do you understand? Yes sir, its range will b

e bigger accordingly. You must have understood the thing. Yes sir, how is Raz defined? If you also feel like extracting it then you can also extract it. Yes sir, have you understood the thing then t byte means 16 byte of 16 yes. Yes and if there is a jab sign in the same. So we use only 15 bits and one bit is reserved for sign for sa. In 15 bits your value will be less and in 16 bits it will be more. Okay, now there will be a line in which you mean. If you do it then you don't have some days to

turn off the internet, then how will the child understand that everything is unsigned, meaning the bit with the V sign is not there, the bit indicating the sign is not there, now you have understood the value of your hope. So this is how much is yours, from zero to 255, from zero to 255, okay, that's it, what is the unsigned cap, if you divide it, then what will be its raj, mine is 1287, okay, you do, and zero to 25 means key . Whatever character there is in me, whatever character there is, ever

ything is in that 256. Do you understand the point? Is there any problem told about A to J, from 65 to where it is till 0, the capital A to J is different, it means 9, what is 99. In the same way, if you continue from 97 onwards, then by the time you reach the root, you will reach where 122. If you have understood about 122, then the value of small a to lekal root kas is from 97 to 122 in the same sequence and then later that It will be converted into a binary number and that thing will be store

d in your computer, okay in the same way as your digit, the value of zero zero case is 48 48 okay one's 49 0 's 50 so you write t but what is it actually? 48 is ji, we will convert it into ok, one means 49 according to the Aki value and it will be converted again into binary number and the same is stored in the computer. Ok, you guys are understanding the point of yours which is also 0 5 s. Whatever number it is, it should also be called Banari. You have to convert it into a number, for that als

o the value is as, okay then what is the enter key, have you guys seen it ? 3 Okay, its value is in the column Sir in the corner 27, in the same way you can know the value of every key, we will write such a program, we will see all the values ​​in C language, if we want to know then how will we know it, we will write a program. Can and know , okay, how much is it in A bit, okay, do you know that you write only A, B, C, D, G from blank English on computer? No, you write in Kannada, Sanskrit, Mala

yalam, Telugu, Chinese, Japanese, Korean, all languages, right, you write all languages. So everything was made in the beginning, the work was going on in AT, everything was in English, okay, the American people made it, okay, this whole system was made, everything was made in English, later gradually I realized that we will not be able to work with plain English, we know all the languages. It is necessary so that every person can use the computer. Okay, so now what happened to those people? Wha

t is the character called? Yes, C programming is not relevant for your knowledge, we are telling it just because we are telling it. Okay, so the computer will not be enough with what it has, brother, you will have to work a little harder, because you have told today's value of ABC CD, now we have to write it in Chinese, let 's look at the Chinese characters , now you have to write all this. Okay, this should also have some value. Yes sir, we have to write Korean, we have to write Canadian alphab

et in Canada, now we are in Bangalore, so let's talk a little more about Canada's alphabet. Okay, so this is what you are understanding, its alphabet is here also. But the way of writing is different. The way of writing is different. We will read it. Its pronunciation is the same. What you read is the same thing in Hindi but the way of writing is different. Okay, anyway, now you know. If you want to write all this, then he said, brother, this 255, my tooth is already filled and this inter keyboa

rd rate comma full stop scape, as much as you are seeing, this is yours, now you have to write all this Chinese, Japanese, Canada, Telugu, Malayalam, Hindi. If you have to write also , where should you write it, then what should be the solution, then say, do this, no, this is the range, no, the 8 bits you have written, one byte, increase it to two bytes, what should you do - bytes are fine, what is the meaning of bytes? 16 bits, 16 bits, okay, since it is 16 bits, where will be the range, please

tell me, how many characters will be there in a byte, how many characters will there be from zero, how many characters will there be, 65535, 65535, you can enter this character, then the remaining amount can be whatever. Everyone has a language. One value can be given for each alphabet. If we increase the range so much, then all the languages ​​of the world will be covered. Everything will be covered. The same has been done in this and it is called Unicode character. What is Unicode character ?

Remember this, we have to tell it now and it will be useful from now onwards. Okay, when we will do HTML, CSS, Java and many other programming categories, we will use these code characters everywhere. Word is okay, when is it necessary to use these code characters. When is there a need to take two bit to byte? When will you need to do? If you have to support any other language other than English. Apart from English, you have to support other languages ​​also. You have to store its character too

and you have to write it too. So what is the data type? You should keep the right byte and byte hat will come later, we will see how to handle it. Got it. Yes sir, yes sir, so how to support the rest of the language, then there is a way to do that, brother, what did they do by bringing unique character and that? We represent in 16 bits, we represent in bits, why because we need more range, yes sir, understood, yes, no problem, come on, sir, this was your ta type, it took too much time to do the

data type, it is ok but hope is full for you guys. You must have understood why there are so many data types, why do you take at byte for character, what is character, how is it converted into binary number, what is the value of a, you have understood all this. Yes sir, we have understood this. If you are going to use it in programming in the future, then you people, keep it with some care, now I have told you that it will be used throughout your life, that is, till you retire, it will be used,

okay, do some programming and use it everywhere. It would be like saying, ABC is the CD, we know how to write anything, that is the ABC of programming, okay, keep this in mind, tomorrow we will do the operator, okay and tomorrow we will finish the operator and may be Holi, after that we will do the next thing. Will start the program ok second one Tell me, if you open the one with head, then what is the meaning of OK with the word 's'? In the word 'I' it means sir, it does not happen in 'Sir', i

t is not in 'Sir', it means that whatever 'B' is written in the computer, it understands it, it considers everyone as 'Kutter', that is why it has to be said 'TaTa' - ' Cutter' Whoever writes anything in me, the one who is writing also understands that everything is a character, write an update, write anything, everything is a character, color and line, everything is a character, for that and the character K is there, I am fine, ta type is needed because of that. So everyone says everything like

no Sab Paseri Yes Sir Yes Yes Sir No so there is another proverb What is Raja Bhoj What is Gangu Teli Kuch to hai Na Raja Bhoj Raja Raja Bhog Raja No No No Sawa Sir What is there at least one proverb Sir, whatever it is is fine, which means that he has nothing to do with anything, everyone understands the same thing, is n't there a P here too, only the cutter understands everyone, even if you write A B C D, one or two. Write three or four , comma, full stop, inter back space, write anything, ev

erything is a character for that, okay, that's why when everything is understood by the character, then what do we have to do, we have to tell the data type, we have to create the data type, understand the thing but Don't consider it to be a minor character, consider it to be an int, consider it to be short and actually consider it to be a character. Understand what is the matter for it. Yes sir, yes, you should understand it as word only. If we have to say it, then what will be the data type fo

r it? Got the point, yes, now understand why the data type has to be mentioned because everything in the computer is the value of vector, vector, and everything which is zero will be converted into one. Yes, okay, when everything is zero, that is all. Then we have to tell something about this being and whatever it is, it has to be calculated differently if characters are given and if numbers are given then it has to be calculated differently so to indicate the same. It is necessary to tell us th

e data type. If we don't tell then Bhai Saheb will treat everyone as a character and do the same work. We are not like that. Yes, fine, there is no other problem, no sir, there is no other thing, we have not seen much, now we are people. Look at the type and the data type of the variable. Look at this much and see nothing more. Today we and you were once again taught why binary numbers were taught, why we talked and you all understood . Why were there these banner numbers and 127 and 128 and 255

? Now I understand, yes sir, yes sir, okay then for today we will keep this only, tomorrow we will continue it and we will give this to you people, right? Wait, every year, every time, it's like every time, otherwise you missed the last one, pin us twice sir, send us the one once, we don't care what to tell on Saturday, what should we send to them, then you People should also keep this in mind, okay, so send a ping once or twice in the group, Sir, Saturday, what did we do on Saturday, what did w

e not do, we don't even care what we did, you people will tell us what we did, then we It is okay to send it again, that is why he did not send it. Now we said, okay, you all must have taken notes, otherwise if you ask someone else, you can also create a group of your own, we do not have any problem. At many places in online classes, people refuse to talk to you, but there is one thing that it is okay for someone who does not want to talk to you, if any of you send him a meaningless message, the

n we will silently let you know. Will throw you out of the class, very simple, okay, if you understand the matter, then you people are intelligent, you people know how to behave with whom, how to talk to whom, don't be fooled by this understanding, okay, otherwise then we will not tolerate that thing. You will be able to do it, okay, talk only to those people who want to talk to you, who are comfortable in talking to you, do not send messages here and there to anyone without meaning, it is okay

even by mistake, the other way around, then it will be very difficult, then you will not be able to stay in the class. Okay , yes, what is not there in reading, we will not think about all that, okay, maintain that behavior in your behavior, if you make any mistake in behavior, then we will not be able to do anything, that is something that cannot be tolerated, okay you. People like this, all of you are free to talk to each other, we do not stop anyone, but never unnecessarily try to talk to any

person or send a message or call him who does not want to talk to you. Whatever may be the reason, have you understood the right thing, yes sir, I have sent it to you guys and you guys are here, now we will meet tomorrow morning in 555, you guys join, don't be late, okay Manish. Kumar, I could not talk to you, perhaps your mic has not been muted yet, yes, Manish, yes, can you tell us a little bit about yourself, what are you doing, where have you joined the class from today itself, sir, if you

have joined from today then we will. Have you understood what you mean by MCA, what course are you doing, MCA , OK, which semester are you in? First semester, first semester OK, have you done direct admission in MC or have you done BCA before? Direct admission is in MCA, not BCA. OK, have you done any computer course before this? If you have done ADCA course then you know a little bit about Word Excel. Okay, you have done ADC course. Thank you. Okay, today we discussed it. You already knew a lit

tle. You knew a little bit. You knew it well. You have understood everything. Okay Aishwarya, you are ready. Come Aishwarya, son, have you understood something? Come sir, okay, were you not in the middle, did you take your name many times? Today the voice is broken, the voice is broken. There is a problem with your network, so please do a little for the network. See which seam to take, what to take, do you live in the village or in the hostel class of your college? Do you live in your village or

live in the college hospital? Where do you live [Music] You okay, your voice breaks a little. Hello ok fine ok anyway so ok we will meet tomorrow and we will continue let's continue thank you thank you bye thank you sir thank you sir [music] [music ] [music] s [music]
