It was thus said that the Great Jim Battle once stated:

The other one I use it for is jumping past the

for (;n;aryp++, n--)
{
printf (", ");
skip_comma:
printf ("%u", *aryp);
}
printf ("\n");

I'd do this, and didn't even know that jumping into the middle of the
FOR loop was legal. Even knowing it is legal, I prefer my way (of course):
void print_ary (int *aryp, int n)
{
int i;
for (i=0; i<n; aryp++, i++)
{
if (i>0)
printf (", ");
printf ("%u", *aryp);
}
printf ("\n");
}
I'd skip both the GOTO and the conditional and do it:
void print_ary(int *aryp,size_t n)
{
size_t i;
char *sep;
assert(aryp != NULL); /* sorry, gotta check */
assert(n > 0);
for (i = 0 , sep = "" ; i < n ; aryp++ , i++)
{
printf("%s%u",sep,&aryp);
sep = ",";
}
putchar('\n');
}
