    #include "stdafx.h"
    #include <iostream>
    #include <string>
    #include <iomanip> // setprecision() funcion
    #include <conio.h> // _getch() function
    #include <ctime> // add system time and date
    using namespace std;
    
    const float interest = 1.67;
    const int cust_account_number = 112280;
    
    string first_name, customer_surname;
    double balance, deposit, withdrawl;
    int account_exists = 0;
    int account_number;
    char dat[10], tim[9];
    
    void display_main_menu();

    Re: Bank Project Problem

    Didn't compiler for me. custome_first_name is undefined. You also have a function called exit declared that you didn't implement.

    You could do yourself a big favor and indent your code consistently and in a way that makes sense.

    exit looks like it will just call itself over and over again until you run out of stack space.
