C | Misc | Question 5

Assume that the size of an integer is 4 bytes. Predict the output?

#include <stdio.h>
int fun()
{
    puts(" Hello ");
    return 10;
}

int main()
{
    printf("%d", sizeof(fun()));
    return 0;
}

(A) 4
(B) Hello 4
(C) 4 Hello
(D) Compiler Error


Answer: (A)

Explanation: sizeof() is an operator, not a function. It looks like a function though.

The operands of operators need not to be evaluated. That is why fun() is not called.
