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.
