  High/Low Game #1

  Copyright (c) 2002 by Keith Fenske.  All rights reserved.

  This Java program plays a simple guessing game.  The computer picks a
  random number from 0 to 100, and the user tries to guess the number.

  This the first (or simplest) version of the High/Low game.  It uses only
  one "do" loop.  Input errors are checked in the same "if" statements as
  the high/low logic of the game.
