#include <stdio.h>
int main()
{
printf ("%x%u\n", 4, 4);
}
> gcc-5 -Wall t.c -Wformat=2
t.c: In function 'main':
t.c:4:11: warning: format '%x' expects argument of type 'unsigned int', but
argument 2 has type 'int' [-Wformat=]
printf ("%x%u\n", 4, 4);
^
t.c:4:11: warning: format '%u' expects argument of type 'unsigned int', but
argument 3 has type 'int' [-Wformat=]
that's undesirable as well (the constant fits in an unsigned int).
