Converting string to char

I got this error in my code I do not know how to figure it out


Cannot convert 'string' to 'char' in function healthClubMaintain::addClient(string)

Code:

#include <iostream>
using namespace std;

class healthClubMaintain{

private:
	 char Al[15];
	string classCleintName;
	int classClientIDNumber;
public:
	void addClient(string);

};


void healthClubMaintain::addClient(string clientName){
	
	classCleintName = clientName;
	
		Al[0]=classCleintName;
	
	   cout << Al[0] << endl;
}


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) Display all clients in the program"<<endl;
	cout<< "(3) Add a new exercise to the program"<<endl;
	cout<< "(4) Display all exercise to the program"<<endl;
	cout<< "(5) Add an approval for an exercise for a client"<<endl;
	cout<< "(6) Display all approval records in the program"<<endl;
	cout<< "(7) Add a performed record to the program"<<endl;
	cout<< "(8) Display all preformed records in the program"<<endl;
	cout<< "(9) Determine for client(s) performance "<<endl;
	cout<< "(10) Exit the program"<<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);
}
}

}

Al[0] is a character, not a string. I don't see a purpose for Al, so maybe you can just remove it; but if you need it somehow change it to a string.

I suppose you want to have vector of strings and not an array of chars (do I have a dejavu?)

even more accurate - you want to have a map<int,string>
which will store pairs Id,Name

Is there any way to do it without using the map thing because it is so complicated for me.

My big concern is that I want to make sure that I stored the values in the array everytime I run the menu until it becomes full.

If you don't like vectors, you can at least use an array of strings (like string ClientNameList[15] or similar instead of char Al[15]).

yeah I am using string array this time, but I am trying to store the values into the array but it doesn't seem working

Code:

void healthClubMaintain::addClient(string clientName){
	
	for(int i=0;i<15;i++)
	{
		Al[i]=clientName;
	}
}

Define "working".

Read your code -- you put clientName into each slot of your array. Do you want clientName in each slot of your array? If not, then why put it there? Presumably you need to figure out which number client this is (a counter, maybe?) and put it in that one slot.

don't you want to store IDs as well?
Make class Client that will have 2 members:
int ID;
string Name;

Make an array (I'd say vector, but you do not like to write a correct C++ code) of Clients

Well I asked my professor and he gave me an easier way to do it. I will need to initial a variable and increment it each time the user will add a new client.. but I still have some problems in the code.. here is my code>>

Code:

#include <iostream>
using namespace std;

class healthClubMaintain{

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

};


// Here is the method ... I need to store my inputs in an array and then print them
void healthClubMaintain::addClient(string clientName){
	counter=0;
	i=0;
	
	if (counter<15){
		Al[counter]= clientName;
	}
	counter++;
	
	while(i<15){ 
		cout<<Al[i];
		i++;
	}
}



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) Display all clients in the program"<<endl;
	cout<< "(3) Add a new exercise to the program"<<endl;
	cout<< "(4) Display all exercise to the program"<<endl;
	cout<< "(5) Add an approval for an exercise for a client"<<endl;
	cout<< "(6) Display all approval records in the program"<<endl;
	cout<< "(7) Add a performed record to the program"<<endl;
	cout<< "(8) Display all preformed records in the program"<<endl;
	cout<< "(9) Determine for client(s) performance "<<endl;
	cout<< "(10) Exit the program"<<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);
	

}
}

}

Well, you set your counter to 0 every time the addClient function is run, so you overwrite the value in the same slot. Again.
You should simply initialize counter to 0 in the constructor and increment it after adding a new client.
Btw, I also mentioned it in the other thread, but indenting your code a little better wouldn't hurt.
