Engineering Computer Science C++ How to Program (10th Edition)

Program plan: Add two new members to class PokerHand1 and PokerHand2, as array of Card Objects. Both Poker hands array contain 5 cards objects in it to be considered as hand to be evaluated. Add one method to evaluate Poker Hand. This method checks for possibility of pair, 2 pairs, three same suits, 4same suits, flush or straight for each Poker hand. It also decides which Hand has better cards. Program Description: This program used functions from exercise 9.24 to deal two five-poker hands and evaluates and determines which is the better hand.
