help in overloading ostream op

[sahm]

hi,
i have to create a program that will print the 52 cards in a deck using
the overloaded ostream operator. it worked fine....then i hve to create
a function that will print the cards in hand in random(5, 10).

//error it shld only have two parameters
ostream& operator<<(ostr eam& out, vector<Card>& deck2, vector<Card>&
hand)
{

for(unsigned int i = 0; i < hand.size(); i++)
{
int random;
random = randNum(0, 51);

//if the card is picked, don't add it in
hand,instead add another card/s in the vector
if(deck2[random].isPicked())
{
deck2[random].printCard(out) ;
out << endl;
int last = hand.size() - 1;
hand.push_back( hand[last]);
for(int i = last; i > deck2[random].isPicked();
i--)
{
hand[last] = hand[last - 1];
}

}

else
{
hand[i] = deck2[random];
deck2[random].setPicked(true );
hand[i].printCard(out) ;
out << endl;
}
}
return out;
}

what shld i put in the parameters of ostream& operator<<(..) in order
to print the card in hand

I think you need to define your problem better.
As you noted operator<< should only have two operands.

You should separate the generation of the hand from the deck
from outputing a hand or a single card. I suggest the following.

First write
ostream << Card;

Then using that also write
ostream << vector<Card>

Then right other functions that make the deck and hands.

I would suggest it would be easier if you actually removed the
cards from the deck after it is picked rather than maintaining
some sort of picked state. Think about the real world you're
attempting to model here.
