Question

Write a C++ program (The Account Class) Design a class named Account that contains (keep the data fields private): a) An int data field named id for the account. b) A double data field named balance for the account. c) A double data field named annualInterestRate that stores the current interest rate. d) A no-arg constructor that creates a default account with id 0, balance 0, and annualInterestRate 0. e) The accessor and mutator functions for id, balance, and annualInterestRate. f) A function named getMonthlyInterestRate() that returns the monthly interest rate. g) A function named withdraw(amount) that withdraws a specified amount from the account. h) A function named deposit(amount) that deposits a specified amount to the account. Implement the class. Write a test program that creates an Account object with an account ID of 1122, a balance of 20000, and an annual interest rate of 4.5%. Use the withdraw function to withdraw $2500, use the deposit function to deposit $3000, and print the balance, the monthly interest.
