Mine

I am trying to overload the < operator and failing. My code is below and the compiler error is below that.

//BEGIN card.h

#include <string>

using namespace std;

class card
{
public:
	card();
	card(int cardFace, string cardSuit);
	bool operator<(const card& rhs) const;	
	int getFace();
	string getSuit();

private:
	int face;
	string suit;
};
//END card.h

//BEGIN card.cc

#include "card.h"

using namespace std;

card::card()
{

}

card::card(int cardFace, string cardSuit)
{
	face = cardFace;

	suit = cardSuit;
}

bool card::operator<(const card& rhs) const
{
	return this->face < rhs->face;
}

int card::getFace()
{
	return face;
}

string card::getSuit()
{
	return suit;
}

//END card.cc

//BEGIN build error
smack@smacktop:~/Desktop/net_cards$ make
g++ -c card.cc
card.cc: In member function ‘bool card::operator<(const card&) const’:
