_Bool in C 👨‍💻

Do we have BOOL in C ?

We do have! and it is widely used in modern embedded projects for better readability, btw many low-level codes still use 0/1 instead of BOOL due to older compiler support, or coding standards.


Since C99:

#include <stdbool.h>

bool flag = false;
if (!flag) {...}

bool is a MACRO for _Bool

You can also use _Bool like this:

_Bool flag = false;
