Programming Challenge 5.21 - Random Number Guessing Game Enhancement

/* Random Number Guessing Game Enhancement - This program generates a
   random number and asks the user to guess what the number is. If the
   user's guess is higher than the random number, the program displays
   "Too high, try again." If the users guess is lower than the random
   number, the program displays "Too low, try again." The program uses
   a loop that repeats until the user correctly guessed the random number.
 
   Enhancement: This program, written in Programming Challenge 5.20 now
   keeps count of the number of guesses. When the user correctly guesses
   the random number, the program displays the number of guesses. */
