Thread: storing data into an array

I want to store 15 names in an array! but it doesn't seem working correctly... anyone can figure it out ?

The problem:
Every time I promote the program to enter a name it will only be stored in the first position in the array. For example, when I promote the program to enter 3 names then print them.. the program will only prints the last input, unlike what it supposed to do and print all inputs

Code:

#include <iostream>
using namespace std;

class healthClubMaintain{

private:
	 string Al[15];
	 string Al2[15];
	 	 
	 int counter,i,s;
	
	int classCleintName;
	int classClientIDNumber;
public:
	void addClient(string);
	void printClient();

};


void healthClubMaintain::addClient(string clientName){
	counter=0;
	
	if (counter ==15){
		cout << " STOP!";

	}
	else{
		Al[counter]=clientName;
		counter++;
	}
		

}

void healthClubMaintain::printClient(){
	
		cout<<Al[0];
		cout <<Al[1];
}




int main(){

int number,loop=0;
int clientIDNumber,programNumber,approvalIDNumber,clientIDA,programNumberA;
string clientName,programName,approvalName;
healthClubMaintain Club;

while ( loop==0){

	cout<< "Select one of the following option:"<<endl;
	cout<< "(1) Add a new client to the program"<<endl;
	cout<< "(2) print"<<endl;

	cin >> number;


if ( number ==1 ){
	cout << "Insert the client's name" << endl;
	cin >> clientName;
//	cout << "Insert a new ID" << endl;
//	cin >>clientIDNumber;
	Club.addClient(clientName);
}

if ( number == 2){
	 Club.printClient();
}

}

}
