<pre>The code:
#include <stdio.h>
void f() {
printf("%.*d", 1);
}
Produces a warning:
main.cpp:3:14: warning: more '%' conversions than data arguments [-Wformat]
printf("%.*d", 1);
~~~^
A format message along the lines of "The specified format indicates 2 data
arguments, but only 1 is received," might be clearer.</pre>
