You may work on this programming project in pairs, if you wish. If you work with someone else, be sure that both of you understand the work that gets done. As before, it is also okay to get help from your friends, the TAs, and/or the instructor if you get stuck, but you should try to do it on your own first. Keep in mind that the goal is not just getting the program to work but learning how to write programs yourself; outside help will not be available to you during the exams. Also remember that you may not work with the same person on more than two of the programming projects for this course.

For this project you will make changes to the BlackJack program.

Improve the style of the BlackJack program:

• Both the player and the dealer in our game have a "hand". As a result, much of the information and functions related to hands are duplicated in the Player and Dealer classes. Design, declare, and define a Hand class and revise the Player and Dealer classes to use it. Will the member functions disappear from the Player and Dealer classes when you add them to the Hand class?

Extend the BlackJack program:

• Modify the BlackJack program to allow aces to represent either a value of one or a value of eleven, depending on which is more advantageous.

• Extend the program so that it resembles more closely a blackjack game as played at a table in a casino. The game can involve up to six players, each of which plays against the dealer using the same rules as before. Use a quadruple deck of cards, and report the final pots of all players once the deck is too small for another round.

Turn in printed copies of the header and implementation files for all classes you modify. Also send e-mail to your lab TA and include these files as an attachment.
