Question

How to I get my twoPair method to work? I am not sure how to check for two separate pairs. I bolded the portion that method.

Also, how do I edit my code to write a program that deals two five-card poker hands, evaluates each, and determines which is the better hand.

Thanks.

Here is my code:

#include

#include

#include

#define SUITS 4

#define FACES 13

#define CARDS 52

//prototypes

void shuffle(unsigned int deck[][FACES]);

void deal(unsigned int deck[][FACES], unsigned int hand[][2], char *wSuit[], char *wFace[]);

void onePair(unsigned int hand[][2], char *suit[], char *face[]);

void twoPair(unsigned int hand[][2], char *suit[], char *face[]);

void threeOfAKind(unsigned int hand[][2], char *suit[], char *face[]);

void fourOfAKind(unsigned int hand[][2], char *suit[], char *face[]);

void flush(unsigned int hand[][2], char *suit[], char *face[]);

void straight(unsigned int hand[][2], char *suit[], char *face[]);

int main()

{

//initialize suit array

char *suit[SUITS] = {"Hearts", "Diamonds", "Clubs", "Spades"};

  

//initialize face array

Explanation / Answer

public static void main(String[] args) { int N = Integer.parseInt(args[0]); String[] suit = { "Clubs", "Diamonds", "Hearts", "Spades" }; String[] rank = { "2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King", "Ace" }; // initialize cards in a deck String[] deck = new String[suit.length * rank.length]; for (int i = 0; i
