Using boolean values in C

Question

C doesn\'t have any built-in boolean types. What\'s the best way to use them in C?

Answer 1

You can simply use the #define directive as follows:

#define TRUE 1
#define FALSE 0
#define NOT(arg) (arg == TRUE)? FALSE : TRUE
typedef int bool;

And use as follows:

bool isVisible = FALSE;
bool isWorking = TRUE;
isVisible = NOT(isVisible);

and so on
