Control Instructions - Programming

Q1:

What will be the output of the program? 
#include<stdio.h>
int main()
{
    char str[]='C-program';
    int a = 5;
    printf(a >10?'Ps\n':'%s\n', str);
    return 0;
}

A C-program

B Ps

C Error

D None of above

ANS:A - C-program

Step 1: char str[]='C-program'; here variable str contains 'C-program'.
Step 2: int a = 5; here variable a contains '5'.
Step 3: printf(a >10?'Ps\n':'%s\n', str); this statement can be written as

if(a > 10)
{
    printf('Ps\n');
}
else
{
    printf('%s\n', str);
}
Here we are checking a > 10 means 5 > 10. Hence this condition will be failed. So it prints variable str. Hence the output is 'C-program'.
