Got it from http://www.genesim.co.il/cprog.htm

For C programmers, here is a C code quiz. You are invited to give it a try.

/*
Find at least 4 different ways to change only one
character in the C code below so it will print the
minus sign "-" 20 or 21 times only.
*/

#include <stdio.h>

main()
{
  int i, n ;
  for(i=0; i<n; i--) printf("-");
  return 0;
}

===========================
I can only know 2 of them,
1. change i-- to n--
2. change i<n to -i<n

Can anyone help me finding the other two? I am very curious...

Thx!
