Oh come on... C has a (very basic) bool type since C99:

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

int main(void) {
    bool a = true;
    bool b = false;

    if (a && !b) puts("hello, bool in C99");    
}
Enter fullscreen mode Exit fullscreen mode

; )

No, the actual Boolean type in C is spelled _Bool. You can use that without including any header. stdbool.h simply defines the macros:

#define bool _Bool
#define false 0
#define true 1

as a convenience.
