Service Pack 5?

Dont know how to check??

Try my workaround wich I posted before your post. I am just gambling but it solves many bugs.

goto help->about msvc (or something like that for info about your ide)

already donethat!
just says vc ++ 6.0 and product id.
I am installing service pack 5 now

Well, how did it react when you did my workaround?

Where should I put
typedef vector<pair<int,int> > VPairs;
VPairs Deck; ??

I put it under card.h before the class card starts and i got 7 errors??

Copy and paste the code below. It is complete so remove what you have now (in card.h).

#ifndef CARD_H
#define CARD_H

#include <iostream>
#include <vector>

using namespace std; 

class Card
{
public:
	Card();
public:
	// Observe the naughty space between > > !
	typedef vector<pair<int,int> > VPairs;
	VPairs Deck;
	VPairs GetDeck()
	{
		return Deck;
	}
	
private:
	enum { Club, Spade, Diamond, Heart} suit;
	
};

Card::Card()
{
	int cardtype;
	for (int i = 0; i < 52; i++)
	{
		// First 13 cards are spades, next 13 are diamonds etc.
		cardtype = i/13;
		switch(cardtype)
		{
			case 0: suit = Club;	break;
			case 1: suit = Spade; break;
			case 2: suit = Diamond; break;
			case 3: suit = Heart; break;
		}
		Deck.push_back(pair<int, int>(suit, 2+i%13));
	}

	//Demonstration of how to iterate through a "vector" holding "pair" objects.
	//It is only one more methods. See "void CardGames::Shuffle()" for the second
	//way of iterating through the vector. 
	for(VPairs::iterator i = Deck.begin(); i != Deck.end(); ++i)
	
	{
		cout<< (*i).first <<" "<< (*i).second<<endl;
	}

} 

#endif //CARD_H

Tried the code u sent now still same errors!

Yes, erm, what I expected. VC6 doesn't support closing of ranges for
variables declared at the beginning of a for statement.

There is a workaround, but I can't test it probably since I don't want to install vc6 (I use 7).
Anyway, change your "print" code and see what happens, in the mean time I'll wait for a friend of mine for your problem:

VPairs::iterator i = Deck.begin();
	for(; i <= Deck.end(); ++i)	
	{
		cout<< (*i).first <<" "<< (*i).second<<endl;
	}

[Valmont]

OMG ROFL
wait!!!
change the i's to j's.!!!

VPairs::iterator j = Deck.begin();
	for(; j <= Deck.end(); ++j	)
	{
		cout<< (*j).first <<" "<< (*j).second<<endl;
	}

On new compilers it doesn't bother but on old(er) it does. LOL.

It works now!! Great!!

Hahaha, the original code was std C++ correct but VC doesn't support it. I made this lil mistake a giga-gazillion times and still fall for it...
I needed to re-think the whole situation going on here!
ROFLMAO.

You can put back the

VPairs::iterator j = Deck.begin()

in the for-loop as well most likely.
You you can change (*). to -> most likely as well.
But leave the typedef intact.

[dirs]

That worked as well!
I will try to do the rest of coding !
Thanks

In The function BlackJack::Shuffle(vector<pair<int,int> > cards)
cout<<cards[i].first<<"_"<<cards[i].second<<endl;
shouldn't it print out the shuffeled deck.
i get
0 2
0 2
all the time instead.

[Valmont]

Insert

srand( (unsigned)time( NULL ) );

in the Shuffle method, between "int k" and the "for" loop.

void BlackJack::Shuffle(vector<pair<int,int> > cards)
{
	pair<int, int> temp;
	int k;
	srand( (unsigned)time( NULL ) );
	for (unsigned int i = 0; i < cards.size(); ++i)
	{
		k=(rand() % 52);
		temp = cards[i];
		cards[i] = cards[k];
		cards[k] = temp;

      // A simple but ugly test. Friends are "helping" me (not)
		//so I need to go soon :(.
		cout<<cards[i].first<<"_"<<cards[i].second<<endl;
	}	
}

Since we are working in std c++, add the <ctime> header on top.
Not <time.h> but <ctime> . If you read a few topics in this forum you will know why.
The "c" word without the ".h" extension is the new standard C++ of adding an 'old' C-based library.
