C++ I got stuck with 2 errors

[changma83]

Hello
I cannot figure out by myself these errors:
error C2143: syntax error : missing ';' before 'using'
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
I surfed the web but I'm still stuck; I believe my problem it's with the Windows Headers.
I looked here( http://msdn.microsoft.com/en-us/libr...(v=VS.85).aspx ) but nothing..
I'm using Visual C++ 2010 Express and my OS is XP 32-bit.

// CODE Cardgame.h
#ifndef CARDGAME_H
#define CARDGAME_H
using namespace std;
#pragma once
class Cardgame
{
int players;
static int totalparticipants;
public:
Cardgame(int p);
~Cardgame(void);
};
#endif

// CODE Cardgame.cpp:
#define NTDDI_WINXP 0x05010000
#define _WIN32_WINNT_WINXP 0x0501
#include "Cardgame.h"
#include <iostream>
using namespace std;

Cardgame::Cardgame(int p)
{
players = p;
totalparticipants += p;
cout << p << " players have started a new game. There are now "
<< totalparticipants << " players in total." << endl;
}
Cardgame::~Cardgame(void)
{
}

// CODE testgame.cpp:
#include <iostream>
#define NTDDI_WINXP 0x05010000
#define _WIN32_WINNT_WINXP 0x0501
#include "Cardgame.h"
int Cardgame::totalparticipants = 0;
int main()
{
Cardgame *bridge = 0;
Cardgame *blackjack = 0;
Cardgame *solitaire = 0;
Cardgame *poker = 0;
bridge = new Cardgame(4);
blackjack = new Cardgame(8);
solitaire = new Cardgame(1);
delete blackjack;
delete bridge;
poker = new Cardgame(5);
delete solitaire;
delete poker;
return 0;
}

Any help that you can provide will be appreciated.
Thanks

Fixed up the header and combined your two .cpp files into one.

Also cleaned up the indention.

No errors when compiling.
