    C++ Operator Overloading help

    I am having problems with my operators that I have overloaded. My current program is probably too long to post here and if i did post it all i doubt anyone would look at it. So I'll just post the errors and some sections of code that might be useful. Thank you in advance for the help. The errors I get are:
    "card.h", line 27.14: 1540-1184 (S) Wrong number of parameters for "operator>".
    a4main.cpp:
    "card.h", line 27.14: 1540-1184 (S) Wrong number of parameters for "operator>".
    "a4main.cpp", line 457.8: 1540-0218 (S) The call does not match any parameter list for "operator!".
    "a4main.cpp", line 457.8: 1540-1283 (I) "builtin operator!(bool)" is not a viable candidate.

    Here are my operators
    For the CARD CLASS:
    Code:
    bool operator!(){
		bool test = false;
		if (this.value == JOKER)
			test = true;
		return test;
	}
	bool operator > (const Card& left, const Card& right){
		bool test = false;
		if (left.value == right.value){
			if (left.suit > right.suit)
				test = true;
		}
		else if (left.value > right.value)
			test = true
		return test;
	}

	bool operator < (const Card& left, const Card& right){
		bool test = false;
		if (right.value == left.value){
			if (right.suit > left.suit)
				test = true;
		}
		else if (right.value > left.value)
			test = true;
		return test;
	}
    For the PLAY CLASS:
    Code:
    	bool operator!(){
		bool test = false;
		if (this.play = 0)
			test = true;
		return test;
	}
	bool operator > (const Play& left, const Play& right){
		bool test = false;
		if (left.play == 0 && right.play == 0){
			if (left.numofcards > right.numofcards)
				test = true;
		}
		if (left.play != 0 && right.play == 0)
			test = true;
		if (left.play != 0 && right.play != 0){
			if (left.numofcards > right.numofcards)
				test = true;
			if (left.numofcards == 1 && right.numofcards == 1){
				if(left.card[0].Face() > right.card[0].Face())
					test = true;
				else if (left.card[0].Face() = right.card[0].Face()){
					if (left.card[0].Suit() > right.card[0].Suit())
						test = true;
				}
			}
			if (left.numofcards == 2 && right.numofcards == 2){
				if (left.card[1].Face() > right.card[1].Face())
					test = true;
				else if (left.card[1].Face() == right.card[1].Face()){
					if (left.card[1].Suit() > right.card[1].Suit())
						test = true;
				}
			}
			if (left.numofcards == 3 && right.numofcards == 3){
				if (left.card[2].Face() > right.card[2].Face())
					test = true;
				else if (left.card[2].Face() == right.card[2].Face()){
					if (left.card[2].Suit() > right.card[2].Suit())
						test = true;
				}
			}
			if (left.numofcards == 4 && right.numofcards == 4){
				if (left.card[3].Face() > right.card[3].Face())
					test = true;
				else if (left.card[3].Face() == right.card[3].Face()){
					if (left.card[3].Suit() > right.card[3].Suit())
						test = true;
				}
			}
			if (left.numofcards == 5 && right.numofcards == 5){
				if (left.play == 5){
					if (right.play < 5)
						test = true;
				}
				if (left.play == 6){
					if (right.play < 6)
						test = true;
				}
				if (left.play == 7){
					if (right.play < 7)
						test = true;
				}
				if (left.play == 8){
					if (right.play < 8 || right.play == 9)
						test = true;
				}
				if (left.play == 9){
					if (right.play < 8)
						test = true;
				}
			}
		}
	}

	bool operator < (const Play& left, const Play& right){
		bool test = false;
		if (right.play == 0 && left.play == 0){
			if (right.numofcards > left.numofcards)
				test = true;
		}
		if (right.play != 0 && left.play == 0)
			test = true;
		if (right.play != 0 && left.play != 0){
			if (right.numofcards > left.numofcards)
				test = true;
			if (right.numofcards == 1 && left.numofcards == 1){
				if(right.card[0].Face() > left.card[0].Face())
					test = true;
				else if (right.card[0].Face() = left.card[0].Face()){
					if (right.card[0].Suit() > left.card[0].Suit())
						test = true;
				}
			}
			if (right.numofcards == 2 && left.numofcards == 2){
				if (right.card[1].Face() > left.card[1].Face())
					test = true;
				else if (right.card[1].Face() == left.card[1].Face()){
					if (right.card[1].Suit() > left.card[1].Suit())
						test = true;
				}
			}
			if (right.numofcards == 3 && left.numofcards == 3){
				if (right.card[2].Face() > left.card[2].Face())
					test = true;
				else if (right.card[2].Face() == left.card[2].Face()){
					if (right.card[2].Suit() > left.card[2].Suit())
						test = true;
					}
				}
				if (right.numofcards == 4 && left.numofcards == 4){
					if (right.card[3].Face() > left.card[3].Face())
						test = true;
					else if (right.card[3].Face() == left.card[3].Face()){
						if (right.card[3].Suit() > left.card[3].Suit())
							test = true;
					}
				}
				if (right.numofcards == 5 && left.numofcards == 5){
					if (right.play == 5){
						if (left.play < 5)
							test = true;
					}
					if (right.play == 6){
						if (left.play < 6)
							test = true;
					}
					if (right.play == 7){
						if (left.play < 7)
							test = true;
					}
					if (right.play == 8){
						if (left.play < 8 || left.play == 9)
							test = true;
					}
					if (right.play == 9){
						if (left.play < 8)
							test = true;
					}
				}
		}
	}

    And this is where the operators are being tested in the testmain
    Code:
    /*Test Card's > operator.  Passed array that holds every card in a deck,
  an array that holds which tests failed and a reference to what test
  number we are on.  returns true if all tests passed
  false otherwise*/

    The ! operator is checked here, this part of the code is line 457 if(!(*c1)){
    Code:
    bool TestCardConstructor(int failedtests[],int& testnumber){
  Card* c1;
  int suitidx,faceidx;                //used to hold index of suit and face
  bool failedmain=false;
  cout << "Testing Card(char,int) constructor" << endl;
  for(int i=0;i<52;i++){
    suitidx=i%4;
    faceidx=i/4;
    char currsuit=(i%3)?SUITS[suitidx]:tolower(SUITS[suitidx]);  //uses the lower
								 //case char once
								 //in a while to
								 //make sure it works
    c1=new Card(currsuit,FACES[faceidx]);                        //create a Card

    if(!(*c1)){                                                  //check ! operator
      failedtests[testnumber]=1;
      failedmain=true;
    Here is the PLAY ! operator
    Code:
    bool TestNotOperator(Play parray[], int failedtests[],int& testnumber){
  bool passmain=true;
  int total=RSIZES[4];                 //total number of Play objects
  cout << "Testing Play's ! operator" << endl;
  for(int i=0;i<total;i++){
    bool notrc=!parray[i];
    if((VALIDPLAYS[i] && notrc) || (!VALIDPLAYS[i]&& (!notrc))){
      passmain=false;
      failedtests[testnumber]=1;
#if VERBOSE==ON
      cout << "The Play's !operator is not working properly" << endl;
      cout << "The operator should have returned "<< ((!VALIDPLAYS[i])?"true":"false")<< endl;
      cout << "Your function returned " << ((!parray[i])?"true":"false")<<endl;
      cout << i << endl;
      Card arr[5];
      int getrc=parray[i].Get(arr);
      PrintCardArray(arr,getrc);

      cout << endl;

    Instead of making any assumptions about your design or what your particular problem is, review the example below and insure you try something similar. Also consider the following couple of notes: 1) different operators require a different number of parameters; 2) if you define an operator inside a class/struct, the first parameter is implied (the object itself); 3) the exception to #2 is if you've actually defined the operator as a friend (because in such a case the function is actually not a member).
    Code:
    class Operators {
  int value;
public:
  // negation operator 
  bool operator!() const;
  
  // addition operator
  int operator+(const Operators &rhs) const;

  // insertion operator
  friend ostream& operator<<(ostream &out, const Operators &obj);
};

// this is a unary operator meaning it has a single argument and
// in this case it is implied; it is used like this: !obj
bool Operators::operator!() const {
  return value == 0;
}

// this is a binary operator; it is used like this: obj1 + obj2
int Operators::operator+(const Operators &rhs) const {
  return value + rhs.value;
}

// this is a binary operator but the first argument is explicitly
// defined because it is not a member function; it
// is used like this: cout << obj << endl;
ostream& operator<<(ostream &out, const Operators &obj) {
  return out << obj.value;
}
