Question

Currently, the game allows players to play as many times as they wish. It does not provide any feedback on how the players are doing, however. Modify the game so that it keeps track of the number of games played as well as the average number of guesses made per game.
To implement this change, add the following list of global variables to the beginning of the script’s Main Script Logic section. Assign each variable an initial value of zero.

$gameCount

• $noOfGuesses

• $totalNoOfGuesses

• $avgNoOfGuesses

Next, modify the Game class’s play game method by adding a statement that automatically increments the value assigned to $noOfGuesses. Finally, modify the programming logic (located in the loop at the end of the Main Script Logic section) that is responsible for prompting players to play again. The required modifications are outlined here:

• Increment $gameCount
• Calculate $totalNoOfGuesses
• Calculate $avgNoOfGuesses

Display two text strings showing the number of games played and the average number of guesses per game
