Algorithms Quiz | SP2 Contest 1 | Question 2

Predict the output of the below C program: 

C

#include <stdio.h>

int main()
{
    int i = 2, j = -2;

    if((printf(\"%d\", j)) < (printf(\"%d\", i)))
       printf(\"%d\", i);
    else
       printf(\"%d\", j);

    return 0;
}

(A)

2-22

(B)

-22-2

(C)

222

(D)

Compilation Error

Answer: (B)

Explanation:

We know that printf() returns the number of character it prints. Hence printf(“%d”,j) will return -2 and newline i.e. 3 characters, and printf(“%d”, i) will return 2 and newline i.e. 2. Thus if statement will look like (3 > 2) which is false. So the else block is executed followed by the execution of printf() statements within the if condition.
