example string cmp

/*
 * FGL - roleplay.FutureGadgetLab.net posted by @alaestor
 * the following is a simple guess the password example
 * without using strcmp or other dedicated string functions.
 * The for() can be compacted to be on one line. Newlined for
 * the 79 char limit. Makes use of in-condition assignment.
