Question

Write a program that reads five cards from the user, then analyzes the cards and prints out the category of hand that they represent.
Poker hands are categorized according to the following labels: Straight flush, four of a kind, full house, straight, flush, three of a kind, two pairs, pair, high card.
To simplify the program we will ignore card suits and face cards. The values that the user inputs will be integer values from 2 to 9. When your application runs, it should start by collecting five integer values from the user. It might look like this (user input is in orange for clarity):
Enter five numeric cards, no face cards. Use 2 - 9.
Card 1:8
Card 2:7
Card 3:8
Card 4:2
Card 5:3
(This is a pair since there are two eights)
Since we are ignoring card suits, there won't be any flushes. Your program should be able to recognize the following hand categories, listed from least valuable to most valuable:
Hand Type
Description
Example
High Card
There are no matching cards, and the hand is not a straight
2, 5, 3, 8, 7
Pair
Two of the cards are identical
2, 5, 3, 5, 7
TwoPair
Two different pairs
2, 5, 3, 5, 3
Three of a kind
Three matching cards
5, 5, 3, 5, 7
Full House
A pair, and a three of a kind
5, 7, 5, 7, 7
Straight
Card values can be arranged in order
3, 4, 5, 6, 7
Four of a kind
Four matching cards
2, 5, 5, 5, 5
(A note on straights: a hand is a straight regardless of the order. So the values 3, 4, 5, 6, 7 represent a straight, but so do the values 7, 4, 5, 6, 3)
Your program should read in five values and then print out the appropriate hand type. If a hand matches more than one description, the program should print out the most valuable hand type.
Here is are two sample runs of the program:
Enter five numeric cards, no face cards. Use 2 - 9.
Card 1:8
Card 2:7
Card 3:8
Card 4:2
Card 5:7
Two Pair!
Enter five numeric cards, no face cards. Use 2 - 9.
Card 1:4
Card 2:5
Card 3:6
Card 4:8
Card 5:7
Straight!
Enter five numeric cards, no face cards. Use 2 - 9.
Card 1:9
Card 2:2
Card 3:3
Card 4:4
Card 5:5
High Card!
Requirements
You must write a method for each hand type. Each method should accept an int array. You can assume that the array will have five elements. The methods should have the following signatures.
boolcontainsPair(int hand[])
boolcontainsTwoPair(int hand[])
boolcontainsThreeOfaKind(int hand[])
boolcontainsStraight(int hand[])
boolcontainsFullHouse(int hand[])
boolcontainsFourOfaKind(int hand[])
You do not need to write acontainsHighCardmethod. All hands contain the highest card. If you determine that a particular hand is not one of the better hand types, then you know that it is a High Card hand.
Suggestions
Test these methods independently. Once you are sure that they all work, the program logic for the complete program will be reasonably straightforward.
