11.7: Customer Accounts Write a program that uses a structure to store the following data about a customer account: Customer name Customer address City State ZIP code Telephone Account balance Date of last payment The program should use an array of at least 20 structures. It should let the user enter data into the array , change the contents of any element , and display all the data stored in the array . The program should have a menu-driven user interface. Prompts And Output Labels. Your main menu should be the following: 1. Enter new account information 2. Change account information 3. Display all account information 4. Exit the program The user is expected to enter 1 or 2 or 3 or 4. The main menu is displayed at the start of the program and after the handling of choices 1, 2 and 3.

Solution

Try this program it may helps you,

#include <iostream>
#include <string>
#include <vector>
#include <iomanip>
using namespace std;

// Globals (Initialization)....

struct Info
{
   string name;
   string address;
   string city;
   string state;
   string zip;
   string tele;
   double balance;
   string date;
};

// using a Global variable here (to keep function calls simple ... to start)

vector < Info > Bank;
bool more();
Info takeIn();
void flushCin();
void newAcc();
void menu();
void showAll();
void editAcc( int );

int main()
{
   for(;;) menu(); // loops forever ... until exit(1) called in menu ...
}

// defaults to no ...
