*
* Overview:  This is a two player number guessing game.  It outputs to the user to enter a secret number, 
* and inputs the users secret number into a variable.  It then loops and outputs to the user how many guesses they have, 
* how many guesses they have left, tells them whether they are too high or low/correct, and changes the range of numbers 
* to reflect the effect that the user's newest guess had on the range of valid numbers.  The program then tells the second 
* user whether they guessed the number correctly or ran out of guesses.  If they are successful the program will tell them so, 
* otherwise the program should tell them what the secret number was and how close their guess was.  
* Finally, it should determine whether or not the user wants to play again.
*
* Input:
* Number of coupons earned.
*
* Output:
* Outputs the number of coupons entered.  The program also outputs the
* number of candy bars and gumballs purchased followed by the remaining number of coupons.
