 13 // Create a higher/lower guessing game using a graphical
 14 // user interface. Allow a user to keep guessing until he
 15 // guesses the number. Choose two colors for your game:
 16 // one should be used to indicate that the value the user
 17 // guessed is higher than the target; the other is used to
 18 // indicate that the value the user guessed is lower than
 19 // the target. With each new guess, change the form color
 20 // based on whether the guess is higher than the target or
 21 // lower. Keep a count of the number of guesses. when the
 22 // the user hits the target, display a MessageBox indicating
 23 // the number of guesses it took. Several approaches can be
 24 // used to seed the target: one is to generate a random
 25 // number by constructing an object of the Random class.
 26 // For example, the following stores a random whole number
 27 // between 0 and 100 in target:
 28 //   Random r = new Random();
 29 //   int target = r.Next(0, 100);
 30 // Turn in your source code for this program.
