Three-Card High-Card

Build a class called ThreeCardHand that is derived from class Hand that was developed during class (and is included with the starter code for this project). Your derived class should include support for comparing two objects of this class to determine which hand "wins" according to the rules of the game.

This game is played between two or more players (just two is sufficient for this exercise). Each player is dealt three cards to make up their hand. The winner is determined according to the highest card in each player's hand. For scoring purposes, follow common ace-high card ordering (i.e. ace is highest, then king, queen, jack, then ten through two).

A template testing program is provided in main.cpp. This program should simulate multiple games between two players. With each game a new Deck object is created and shuffled. Modify the main function to declare two ThreeCardHand objects, deal three cards to each, display both (use the str method), and determine which wins.

Do not modify cards.h or cards.cpp. You should modify the main function in main.cpp to complete the test program. Your may choose to implement your derived class in main.cpp or its own header and implementation file pair.
