I know set is bool. But that should not matter, code is okay and
compiler will do the right thing:
pavel@amd:/tmp$ cat delme.c
#include <stdbool.h>
void main(void)
{
bool a = false;
int b = a;
}
pavel@amd:/tmp$ gcc -std=c99 -Wall delme.c
delme.c:3:6: warning: return type of ‘main’ is not ‘int’ [-Wmain]
void main(void)
^
delme.c: In function ‘main’:
delme.c:6:7: warning: unused variable ‘b’
[-Wunused-variable]
int b = a;
^
Best regards,
Pavel
