Question

You have been hired as a programmer by a major bank. Your first project is a small banking transaction system. Each account consists of a number and a balance. The user of the program (the teller) can create a new account, as well as perform deposits, withdrawals, and balance inquiries. The application consists of the following functions:

 N- New account

 W- Withdrawal

 D- Deposit

 B- Balance

 Q- Quit

 X- Delete Account

Use the following function to produce the menu: void menu(); Your task for this tutorial is develop that function which displays the menu. The main program then prompts the user for a selection. You should verify that the user has typed in a valid selection (otherwise print out an error message and repeat the prompt).

CAN SOMEONE PLEASE WRITE THIS PROGRAM IN C++ AND MAKE SURE IT WORKS- IVE BEEN LOOKING AT SIMILAR PROGRAMS THAT ARE ALREADY ON CHEGG BUT THEY ALL HAVE ERRORS. USUALLY STATING "NO SUCH FILE OR DIRECTORY". THANK YOU

Sample output:

Program code to copy:

#include<iostream>
using namespace std;

//make Account number & Balance Global variable because we need them in every function
string accountNo;
double balance;

//A function for showing menu to the user
void menu(){
   cout<<"\n\t\t\tN- New account"<<endl;
   cout<<"\n\t\t\tW- Withdrawal"<<endl;
