Size of short integer and long integer can be verified using the sizeof() operator.

[A]. True
[B]. False

Answer: Option A

Explanation:

True, we can find the size of short integer and long integer using the sizeof() operator.
Example:


#include<stdio.h>
int main()
{
    short int i = 10;
    long int j = 10;
    printf("short int is %d bytes.,\nlong int is %d bytes.",
            sizeof(i),sizeof(j));
    return 0;
}

Output:
short int is 2 bytes.
long int is 4 bytes.

What is the function of return 0? please anyone explain?

If we use int main() it is necessary to use return 0.

It is used to return the main function again and again.

Is sizeof(i), size(j) predefined in library? I mean are they inbuilt function?

Here, int main () it returned the main function again and again.
