I need some help in writing this program that plays 10 hands of Poker and outputs to the user what his hand is.
The problem I'm having is trying to find out how to use suitsInHand[SUITS] and facesInHand[FACES] as counters for suits and faces in a hand.
Quote:
suitsInHand is 4 counters that represents how many hearts, clubs, diamonds, spades are in the hand. These 4 counters must add up to 5. For example if you have 5 hearts in the hand of cards, the array would have the values 5,0,0,0
facesInHand is 13 counters, that represent how many two’s, three’s, etc. you have in the hand. This must also total 5. For example, if you have a pair of 3’s, and three Kings’s, this array would have the values 0,2,0,0,0,0,0,0,0,0,3,0
While dealing a hand of cards, keep a count of the suitsInHand, and facesInHand.
Code:
