Illegal character errors

I am sorry my code looks really long but I got some errors in this part that I coudn't really fiqure them out, which they are the following:



[CODE]Warning W8054 Program3.cpp 115: Style of function definition is now obsolete
Error E2316 Program3.cpp 115: 'healthClubMaintain::approvalExerciseToClient()' is not a member of 'healthClubMaintain'



for this part

Code:

void healthClubMaintain::approvalExerciseToClient(exerciseName1){
	int flag = 0; // set flag to off

	for(int i=0; i<15; i++){
		if (names[i] == exerciseName1){
			flag = 1;
			break ; 
		}
	}
	
		if (flag){
			cout<< "Your number is at subscript position " << i << endl;
		}
	
		else{
			cout<< "Sorry, I could not find your number in this array."<<endl;
		}
	 
}

This is my original code

Code:

#include <iostream>
using namespace std;

class healthClubMaintain{

private:
	 string names[15];
	 int idnumbers[15];
	 
	 string exerciseNames[15];
	 int exerciseidNumbers[15];

	 int counter,counter2,counter3,counter4,counter5,i,s,q,w,x,z,flag1;
	 string mystr;


public:
	void addClient(string,int);
	void printClient();
	void printClientID();
	void addExercise(string,int);
	void healthClubMaintain::printExercise();
	void approvalExerciseToClient(string);
	healthClubMaintain() {  // default constructor
    counter5 = 0;
	 counter4 = 0;
    counter3 = 0;
	 counter2 = 0;
	 counter=0;
}

};


void healthClubMaintain::addClient(string clientName, int clientIDNumber){
	mystr = clientIDNumber;
	
	if (counter<15){
		names[counter]=clientName;
		counter++;
	}
	
	while(counter3<10){
		if ( (mystr[counter3] != '1') || (mystr[counter3] != '2') ||(mystr[counter3] != '3') || (mystr[counter3] != '4') ||(mystr[counter3] != '5') || (mystr[counter3]!= '6')||(mystr[counter3] != '7') || (mystr[counter3] != '8')||(mystr[counter3] != '9'))
		{
			flag1=1;
			break;
		}
		counter3++;
	}
	
	if(flag1){
		if (counter2<15){
			idnumbers[counter2]=clientIDNumber;
			counter2++;
		}
	}
	else{
		cout << " Error!"<<endl;
	}
	
	
}
	


void healthClubMaintain::printClient(){
		
		i=0;
		s=0;
		while(i<counter){
			cout << "client's name:  " << names[i]<<endl;
			cout << "ID#:  " << idnumbers[s]<<endl;
			cout << "  " <<endl;
			i++;
			s++;
		}

	
}

void healthClubMaintain::addExercise(string exerciseName, int exerciseNumber){
	
	if (counter4<15){
		exerciseNames[counter4]=exerciseName;
		counter4++;
	}
	

	if (counter5<15){
		exerciseidNumbers[counter5]=exerciseNumber;
		counter5++;
	}

	
}
	


void healthClubMaintain::printExercise(){		
		q=0;
		w=0;
		while(q<counter4){
			cout << "Exercise's name:  " << exerciseNames[q]<<endl;
			cout << "Exercise#:  " << exerciseidNumbers[w]<<endl;
			cout << "  " <<endl;
			q++;
			w++;
		}

	
}


void healthClubMaintain::approvalExerciseToClient(exerciseName1){
	int flag = 0; // set flag to off

	for(int i=0; i<15; i++){
		if (names[i] == exerciseName1){
			flag = 1;
			break ; 
		}
	}
	
		if (flag){
			cout<< "Your number is at subscript position " << i << endl;
		}
	
		else{
			cout<< "Sorry, I could not find your number in this array."<<endl;
		}
	 
}

				



int main(){

Give the function parameter a type. Move the i declaration out of the loop if you want to use it after the loop. Match up your curly braces.

When you see something like this:

Code:

}

}
}

Then you have an indentation problem.
Refer to http://cpwiki.sf.net/Indentation for indenting or select all code and press Alt+f8 inside visual studio to indent better.

All arguments must have a type in C++, so you get that error because you omitted the type, hence the compiler skipped the argument but couldn't find a function in the class that takes no arguments.
