I just finished my second year of my three year programming course at college. On the break I am gonna go back and update some old programs I have done in the past to keep my skills fresh. I am gonna start with a blackjack program I did a couple years ago. I want to add inheritance to my classes, and wanted a bit of input b4 I do my overhaul. Here is the previous structure :

(Toggle Plain Text)

class Dealer
{
private:
  std::vector<Card> vecShoe;
  std::vector<Card> vecHand;
  int total;
public:
  Dealer(); 
  std::vector<Card> GetHand();
  void RecieveCard(); 
  int GetTotal();
  void ShuffleDeck();
  void LoadDeck();
  Card DealCard();
};

class Player
{
private:
  std::vector<Card> vecHand;
  int total;
  int money;
public:
  Player();
  std::vector<Card> GetHand();
  void RecieveCard(Card card);
  int GetTotal();
  int GetMoney();
  void SetMoney(int money);
};

If you need more info on the functions let me know. I want to add some inheritance. Do you guys think there is even a point to doing inheritance on this example? I guess there is a couple similar functions, but is there enough to even bother making a base class and all that stuff? Let me know what you guys would do with this to clean it up and make it better.

I guess if I simply wanted to add inheritance I could just go:

(Toggle Plain Text)

class Dealer
{
private:
  std::vector<Card> vecShoe;
protected:
  std::vector<Card> vecHand;
  int total;
public:
  Dealer(); 
  virtual std::vector<Card> GetHand();
  virtual void RecieveCard(); 
  virtual int GetTotal();
  void ShuffleDeck();
  void LoadDeck();
  void PrintDeck();
  Card DealCard();
};

class Player: public Dealer
{
private:
  int money;
public:
  Player();
  std::vector<Card> GetHand();
  void RecieveCard(Card card);
  int GetTotal();
  int GetMoney();
  void SetMoney(int money);
};

Well, a dealer is just a player with a special set of rules.. so start there.

I think you've got your inheritance backwards. A Dealer is a form of a Player, but a Player is not a form of a Dealer.
