How do I get classes within a class???

Feb 18th, 2009

For instance... I have the class Deck, which represents a deck of cards, and I want another class, derived from that, called cards, I want class Deck to have a class array called Cards[52], so I can assign all the different values and strings to the individual Cards class instances and have the class Deck do things to the deck as a whole... Im talkin something like this

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
class Deck{
protected:
class Cards[52];   // This doesnt work to have multiple instances in the class
 
public:
void Shuffle();
 
};
 
class Cards : public Deck{
Cards(int,string);
};
class Deck{
protected:
class Cards[52];   // This doesnt work to have multiple instances in the class

public:
void Shuffle();

};

class Cards : public Deck{
Cards(int,string);
};

ik that you might not understand why i want to do this in two different classes, but i do... so please just gimme a clear cut answer. please and thank you!

Don't define class Card within class Deck.
Create a card class.
Then let deck class contain an array of card objects

class Card {
string suit;
int value;
///more stuff
};

class Deck{
Card theDeck[52];
//more stuff
};

I figure anything that irritates liberals is worth my support.

When I had to use two classes that interlaced, I wrote my first class out, then wrote the second class out, then had a variable in the second class that called the first class. For your example, I would write out what you want class Card to do. Then write out what you want class Deck to do, and when you know where they overlap, use a variable that jumps between the classes.

For me, I'm going to call my classes Deck and PCards so I can make sure it all makes sense. So, say you want class Deck to shuffle the cards. You would try something like this:

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
PCards Shuffle (PCards cards[], int 52) 
{
   cards.randomize();
   return cards;
}
PCards Shuffle (PCards cards[], int 52) 
{
   cards.randomize();
   return cards;
}

Where they would be a function in class PCards that would randomize them. Now, that's just off the top of my head, and I don't know what you are trying to do, but that's how I handled having two classes.
