Question

I need to make a poker game for school in c++.
I have made a class Card and Deck.
I need to make a doubly linked list of all the cards, and every card has a suit and a rank (value). How can I attach 2 attributes (suit and rank) to a Card in a doubly linked list.

Answer 1

A double linked list is a structure (a struct or a class) with pointers to the previous and the next link. In addition to these pointers you can add arbitrary data, which can be considered the payload. There you can put any data you want. Here is an example:

class Card {
    public:
       // Constructor
       Card(int rank, int suit, Card* prev=NULL) 
       {
           if (prev)
           {
             m_prev = prev; 
             prev->m_next = this;
           }
           m_prev = prev;
           m_rank = rank;
           m_suit = suit;
       }
       // Accessors
       int Rank() { return m_rank; }
       int Suit() { return m_suit; }
       Card* Prev() { return m_prev; }
       Card* Next() { return m_next; }

    private:
       int m_rank, m_suit;
       Card *m_prev, *m_next;
}
