declaring and using a string in a header file

[codie1990]

i am tring to declare and use a string in a header file

#ifndef DECK_H
#define DECK_H

#include <vector>
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <string>

struct aCard
  {
	  int Suit;
	  int Rank;
  };

class Deck  
{  
public:  
    void initialiseDeck();  
    void displayDeck();  
    void shuffleDeck();   
	void drawCard();
	void getSuit();
	void getRank();
	string suitString;
	std::vector<aCard> Cards;
    Deck();  
    ~Deck(); 

private:
}; 

#endif 

this is my header file so far, however it thows up errors whenever i try to compile moaning about the string line.

Does anyone know why?

Any help is much appreciated =)

It's std::string.

Or you can simpley type "using namespace std;" right after you include all of your files

#include <vector>
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <string>
using namespace std;
