    Question Need help with program for class

    Hello everyone. I知 in desperate need for some help with my problem. First a little background info. The first part of the assignment was to create a program that would take a deck of cards shuffle them, deal a hand, and determine if there was a two pair, three pair, flush.... ect. I was able to knock that program out pretty easily. But the second part of the program is killing me. The second part of the program requires me to have the program a second hand, determine what both hands have and then state which hand would win. I have no clue on how to do this and every time I email the teacher for help, she just confuses me more. If any of you coders out there could tell me how to do this, it would be greatly appreciated. And if you could explain in detail, it would help since I知 still new and learning.

    Here is the code for the first part:
    Code:
    // Fig. 5.12 
    // Card shuffling dealing program 
    #include <iostream>
    #include <conio.h>
    
    using std::cout;
    using std::ios;
    using std::endl;
    
    #include <iomanip>
    
    using std::setw;
    using std::setiosflags;
    
    #include <cstdlib>
    #include <ctime>
    
    void shuffle( int [][ 13 ] );
    void deal( const int [][ 13 ], const char *[], const char *[], int [][ 2 ] );
    void pair( const int [][ 13 ], const int [][ 2 ], const char *[] );
    void threeOfKind( const int [][ 13 ], const int [][ 2 ], const char *[] );
    void fourOfKind( const int [][ 13 ], const int [][ 2 ], const char *[] );
    void flushHand( const int [][ 13 ], const int [][ 2 ], const char *[] );
    void straightHand( const int [][ 13 ], const int [][ 2 ], const char *[], const char *[] );
    int main()
    {
    const char *suit[ 4 ] = 
    { "Hearts", "Diamonds", "Clubs", "Spades" };
    const char *face[ 13 ] = 
    { "Ace", "Deuce", "Three", "Four",
    "Five", "Six", "Seven", "Eight",
    "Nine", "Ten", "Jack", "Queen", "King" };
    int deck[ 4 ][ 13 ] = { 0 }, hand[ 5 ][ 2 ] = { 0 };
    
    srand( time( 0 ) );
    
    shuffle( deck );
    deal( deck, face, suit, hand );
    pair( deck, hand, face );
    threeOfKind( deck, hand, face );
    fourOfKind( deck, hand, face );
    flushHand( deck, hand, suit );
    straightHand( deck, hand, suit, face );
    
    
    return 0;

    Do I really gotta read all of that? If you are gonna post an entire program, could you comment it a little? It'd make everything a lot easier.

    I just scanned over it, but why cant you make two "hand" arrays, deal into one hand, then deal into the other hand, check both of them, and decide who has the better hand?

    You need some way to rate a hand. There are many ways to do it. One is to use an enum:
    Code:
    enum score{zilch, pair};
    
    score player1 = pair;
    score player2 = zilch;
    
    if(player1 < player2)
      cout << "player2 wins" << endl;
    else if(player2 < player1)
      cout << "player1 wins" << endl;
    else
      cout << "draw" << endl;
    Another way would be to use a struct/class to represent a player. The player has a hand of 5 cards. The type of hand he has is assigned a value.

    Code:
    struct Player{
    {
       cards hand[5];
       int value;
       int assignValueToHand();
    };
    
    int Player::assignValueToHand()
    {
       if(isZilch(hand))
         value = 0;
       else if(isPair(hand))
         value = 1;
    }
    where isZilch() and isPair() have bool return

    You can even be more creative and indicate that a pair of Aces beats a pair of Kings, and a royal flush 10 high looses to a royal flush jack high, and royal flush 10 high in hearts looses to a royal flush 10 in spades, etc.
