I am writing a card program for my C++ class that uses two classes. It creates a deck of cards and shuffles them. A user picks a card and the computer picks a card. If the user picks a higher card number he wins and if not he loses. I can create the deck and shuffle it fine.

I am trying to make main as small as possible by utilizing the two classes one for cards and the other for the game. I am struggling on having the two classes work together to display the card the user and computer picks and passing the chosen cards to member functions of the game class. I am using an array of objects for my deck and accessing them and sending them to Card::Display().

Many of the compile errors deal with accessing private data between the two classes. I know I either do not have my game class set up right or I am passing data the wrong way. If anyone could point me in the right direction I would really appreciate it. Thanks.

the fallowing is my code. I hope is is easy to understand. It compiles correctly but does not display the card.

#include <iostream.h>
#include <stdlib.h>
#include <ctime>
using namespace std;

//Creating number system for cards
const int Jack = 11;
const int Queen = 12;
const int King = 13;
const int Ace = 14;
enum Suit {Spades, Hearts, Diamonds, Clubs};

//Individual Card
class Card
{
private:
int number;
Suit suit;
public:
Card()
{}
void setcard(int card, Suit s)//Sets card into Deck
{number = card; suit = s;}
Card CreatDeck(Card TempDeck[52]);
void Display();

};

class Game //Class for game
{
private:

public:
Game()
{ }
int CardChoice(int u, int c)//Aloows a user to choose a card
{
do{cout << "Pick a card from 0 to 52: ";
cin >> u;}
while(u < 0 || u > 52);
do{c = rand() % 52;}
while(c == u);
return u, c;
}

};

Card Card::CreatDeck(Card TempDeck[52])//creates deck and shuffles the deck
{
int a;
for (a=0; a<52; a++)//Ordered Deck
{
int c = (a%13)+2;
Suit s = Suit(a/13);
TempDeck[a].setcard(c, s);
}
for (a=0; a<52; a++)//Shuffled Deck
{
int t = rand() % 52;
Card temp = TempDeck[a];
TempDeck[a] = TempDeck[t];
TempDeck[t] = temp;
}
return TempDeck[52];
};

void Card::Display()//display the card
{
if( number >= 2 && number <= 10 )
cout << number;
else
switch(number)
{
case Jack: cout << "J"; break;
case Queen: cout << "Q"; break;
case King: cout << "K"; break;
case Ace: cout << "A"; break;
}
switch(suit)
{
case Clubs: cout << static_cast<char>(5); break;
case Diamonds: cout << static_cast<char>(4); break;
case Hearts: cout << static_cast<char>(3); break;
case Spades: cout << static_cast<char>(6); break;
}
}

int main()
{
int User, Computer;
User = 0; Computer = 0;
srand(time(NULL)); //Initalization of Random Number Generator
