What am I supposed to do here? Please help!

Hi,

I have the following program:

#include <iostream.h>
#include <stdlib.h> // for randomize(), rand
#include <time.h> // for randomize()
#include <conio.h> // for getche()

enum Suit { clubs, diamonds, hearts, spades };

const int jack = 11; // from 2 to 10 are
const int queen = 12; // integers without names
const int king = 13;
const int ace = 14;

class card
{
private:
int number; // 2 to 10, jack, queen, king, ace
Suit suit; // clubs, diamonds, hearts, spades
public:
void init(int n, Suit s) // initialize card
{ suit = s; number = n; }
void 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 << 'c'; break;
case diamonds: cout << 'd'; break;
case hearts: cout << 'h'; break;
case spades: cout << 's'; break;
}
} // end display()
}; // end class card

void main()
{
card deck[52]; // deck of cards
int j = 0; // counts thru deck
int num; // card number

cout << endl;
for(num=2; num<=14; num++) // for each number
{
deck[j].init(num, clubs); // set club
deck[j+13].init(num, diamonds); // set diamond
deck[j+26].init(num, hearts); // set heart
deck[j++ +39].init(num, spades); // set spade
}

cout << "\nOrdered deck:\n";
for(j=0; j<52; j++) // display ordered deck
{
deck[j].display();
cout << " ";
if( !( (j+1) % 13) ) // newline every 13 cards
cout << endl;
}

srand(time(0)); // seed random number generator
for(j=0; j<52; j++) // for each card in the deck,
{
int k = 1 + rand() % 52; // pick another card at random
card temp = deck[j]; // and swap them
deck[j] = deck[k];
deck[k] = temp;
}

cout << "\nShuffled deck:\n";
for(j=0; j<52; j++) // display shuffled deck
{
deck[j].display();
cout << " ";
if( !( (j+1) % 13) ) // newline every 13 cards
cout << endl;
}
getch(); // wait for keypress
} // end main



This is from a book I am doing. Now, at the end of the chapter, there's this excersize and I can't find a way to do it.

Exercise 1
Revise the main() part of the CARDADAY program so that, after shuffling the deck, it deals a hand of 13 cards to each of four players (as in bridge). A player can be represented by an array holding that player’s cards. After dealing the four hands, display them.

The part were I have to create an array for each player without editing the class is confusing me :(

Anybody kind enough to show me at least what I should do? ( not the actual code :) )

Thanks,
Marc

Create 4 player arrays which will hold 13 cards.
Then use a loop which will deal each player 13 cards. Deal one card to player 1, then player 2, then player 3, then player 4. Repeat this until each player has 13 cards.

A second option is to create a two-dimensional player array, enough to hold 4 players of 13 cards each.

How may I assign the 13 cards to the array?
To do that I need to access the data in the class. However, there in no member function that returns them.

What should I do?

Marc

Then make the method.
