Sir you are...just just just just just just just just just just just just just just just just just just just just just just just just just just just just just just just just just just just.......... awesome sirrrr..........😊
because the sizeof integer is 4 bytes means var = 4 in the c99 standard if the type is not a variable length array inside the sizeof(..) is not evaluated, so the result is 5 4
Sir, i understand how the 5 is getting printed but i don't understand how the 4 is getting printed. It would be very kind of you if you explain this to me.

No, any data type which doesnt have varying size. Example, arrays have varying length so arrays are evaluate but i++ is only variable and we know var is either 2 or 4 according to 32 or 64bit computer but either way it's a constant size so sizeof doesn't evaluate what is inside of it if data type is fixed length this is what I understood correct me if I'm wrong.
It says, in the very question, that the size of integer is 4, so, 5=4, 6=4, 7=4 and so on and since var equals to the size of 6, which is 4, the ouput for var is 4.

Same here
Please tell me what should I do to excel in my bca classes. I want to be good at studying and score well. Please give me some tips 🙏
Love love love your way of teaching. God bless you sir❤️
We want this only
Please increase your team strength
And upload videos more fastly
Thank u
excellent. sir upload lectures on a regular basis. very helpful
A) because no increment or decrement operation perform inside sizeof function, so i will ramain 5 and its size is 4. therefore ans is 5 4
Simply I++ or I-- is not performed inside the "sizeof" operator....
Then how can it get 4 after 5

some people dislike this video cuz they thought it was the download buttom,

I think the sir who is teaching now is different from tge sir who teaches digital and ana analogue electronics. Is it true? Please clarify.
Wow like a suspense movie 🎬 .. well played 👌

5 4 is answer
great question
Where i can get these type of questions for practice sir.
bow down in respect
thank u
excellent
Answer is 5 and 4
I have a question you said c11 is the latest version and you're providing facts from c99 ?
Sir, can you pls tell me how the var value becomes 4 ?
because the sizeof integer is 4 bytes means var = 4 in the c99 standard if the type is not a variable length array inside the sizeof(..) is not evaluated, so the result is 5 4
Thank u hicham
the answer is 54

Super sir
Legend sir
Thank you sir for the video. But in turbo c,output :5 2.Plz reply why it so.
It's compiler dependent... If you are using 16 bit compiler, you will get 5 2... If you use 32 bit, then the answer will be 5 4...
the size of integer in your Compiler is 2, thats why you get 5 2. hope you understand.
@@shaikjohnybasha2689 16 bit? or u mean 64 bit i dont think anyone uses 16bits anymore
TRUE
5 4
what if it was ++i ??
++a Pre - increment operator
a++ post -increment operator ....
- - a pre - decrement operator
a - - post - decrement operater.....
Even then the sizeof prints 2 or 4 according to specs of machine since ++i is still an integer and integers are constant to your machine.
How 4 has printed?
Because integer is 4 bytes sizeof(i++) which is integar is 4....
only i++ , ++i,i--,--i are not evaluated within sizeof() ???
Can you tell me how the var value becomes 4..pls

How you get 4 sir in answer
It says, in the very question, that the size of integer is 4, so, 5=4, 6=4, 7=4 and so on and since var equals to the size of 6, which is 4, the ouput for var is 4.
The size of int in your system is 4byted so .it can vary from system to system
