Introduction

C99 introduced a _Bool type to store a Boolean value, which is a value that can only be either 1 (true) or 0 (false). 

#include <stdio.h>

int main() {

    _Bool b = 0; /* false value */
}

_Bool is usually accessed via its alias name bool defined by the standard header stdbool.h.

This header also defines the macros true and false as aliases for 1 and 0.

Demo Code

#include <stdbool.h>
#include <stdio.h>

int main() {/*w  w  w .  j  a v a 2  s  . com*/
    bool b = true; /* true value */
}
