Does the C standard explicitly indicate truth value as 0 or 1?

Question

We know that any numbers that are not equal to 0 are viewed as true in C, so we can write:

int a = 16;

while (a--)
    printf(\"%d         


        

Answer 1

It happened because of the Relational Operators in your printf statement.

Operator == and operator !=

Since (0 == 0) holds true so, it gives a value 1

whereas, (0 != 0) doesn't hold true so, gives a value 0 .
