[c-prog] %hhu

[[e-mail] [c-prog]]

Is the following code correct? Or does it has a bug?


#include <stdio.h>


int main ()
{
unsigned char p0, p1;
printf ("Enter 2 values separated by ; ");
scanf ("%hhu;%hhu", &p0, &p1);
printf ("I understood %hhu;%hhu\n", p0, p1);
return 0;

}

Technically it's correct, but why you'd want to place user input into chars
is potentially questionable.

Personally I don't use scanf unless there is formatted input. I actualy
use fgets myself directed to stdin. That might be a little unusual. but
it works for me :) Gets can overflow and has I guess, been removed from
the standard.
