Output of following C code will be?

C




#include <stdio.h>
int main()
{
   int a = 0;
   int b;
   a = (a == (a == 1));
   printf("%d", a);
   return 0;
}


(A)

0

(B)

1

(C)

Big negative number

(D)

-1



Answer: (B)

Explanation:

We need to figure out value of “(a == (a == 1))” 

(a == 1) returns false as a is initialized as 0. So in outer bracket, false is compared with a. Since a is 0, result of of outer bracket becomes true. 

The important thing to note is, in C, when a boolean value is compared or assigned to an integer value, false is considered as 0 and true is considered as 1.
