C | Loops & Control Structure | Question 6

#include <stdio.h>
int main()
{
    int i;
    if (printf("0"))
        i = 3;
    else
        i = 5;
    printf("%d", i);
    return 0;
}

Predict the output of above program?
(A) 3
(B) 5
(C) 03
(D) 05


Answer: (C)

Explanation: The control first goes to the if statement where 0 is printed. The printf(“0”) returns the number of characters being printed i.e. 1. The block under if statement gets executed and i is initialized with 3.
