#include <stdio.h>
enum class Enum : unsigned short {
One,
};
void test(Enum e) {
printf("0x%04hx", e);
}
gcc:
<source>: In function 'void test(Enum)':
<source>:8:12: warning: format '%hx' expects argument of type 'int', but
argument 2 has type 'Enum' [-Wformat=]
printf("0x%04hx", e);
^~~~~~~~~ ~
Compiler returned: 0
