Spara rätt summa till rätt användare

Tjenare! 

Jag håller på att skriva ett program som fungerar som bank.

Man skapar konto osv dock vet jag inte hur jag ska få till Array funktionen till summorna för rätt konot om man säger så.

Jag vet inte hur jag använder mig av samma metod som jag har till namnen och kontonummer till depositen och uttagen så det inte blir för alla användare utan bara för den som vill göra insättningen eller uttaget. Hoppas någon kan hjälpa mig med lite tips!

// Här kommer koden som jag har än så länge.

#include <iostream>
#include <string>

using namespace std;

class Bank {
private:
const int m = 100;
string Name[100] = {};
string AccNum[100] = {};
string AccType[100] = {};

double Initial, Withdraw, Deposit;

public:
Bank() {
const int m = 100;
string Name[100] = {};
string AccNum[100] = {};
string AccType[100] = {};
Withdraw = 0;
Deposit = 0;
Initial = 0;

}
void meny();
void create();
void depo();
void check();
void wdraw();
void display();
void Exit();

};

void Bank::meny() {
int choice;
cout << "*****************************************************************\n" << endl;
cout << "\t\t Bank Management System \n\n " << endl;
cout << "\t Choose from the meny below: " << endl;
cout << "\t\t 1. Create an account " << endl;
cout << "\t\t 2. Deposit money " << endl;
cout << "\t\t 3. Check Balance " << endl;
cout << "\t\t 4. Withdraw Money " << endl;
cout << "\t\t 5. All Accountholders detail " << endl;
cout << "\t\t 6. Exit " << endl;

cout << "*****************************************************************\n" << endl;

if (choice == 1) {

}

void Bank::display() {

int counter = 0;

cout << "\t Deposit: " << Deposit << " Withdraw: " << Withdraw << " Balance: " << Initial << endl;
}
