Question

Write a program called problem4.cpp to implement an automatic teller machine (ATM) following the BankAccount class the we implemented in class. Your main program should initialize a list of accounts with the following values and store them in an array Account 101 → balance = 100, interest = 10% Account 201 → balance = 50, interest = 20% Account 108 → balance = 200, interest = 11% Account 302 → balance = 10, interest = 5% Account 204 → balance = 250, interest = 12% The program would ask the user to enter an account number, displays the account balance if the account exists, or an error if it doesn’t, then prompt the user to choose an operation from following 1) Deposit 2) Withdraw 3) Check Balance 4) Add Interest 5) Exit The follow-up scenario depends on each operation (e.g. for a withdrawal, your program should ask for the amount to withdraw, then either print an error if the withdrawal is bigger than the balance or an operation completed if it is less). After operations 1,2,4, the program should display the updated balance. When the user chooses to exit, the program should return to the main prompt of asking the user to enter an account number The program should terminate if the user input -1 in the account number field (35 points)
