'goto" gone from computer languages or is it!

  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');
	}
