1. Derived classes of Account)In Week 9 Lab Exercise 1,we created the Account class
to model a bank account. An account has the properties account number, balance, and annual interest rate, and functions to deposit and withdraw.Create two derived
classes for checking and savings accounts.A checking account has an overdraft limit
but a savings account cannot be overdrawn.Also, a savings account has a maximum deposit limit.Define a constant virtual tostring() function in the Account class and override it in the derived classes to return the account number and balance as a string. Draw the UML diagram for the classes Implement the classes
Write a test program that creates objects of Account, SavingsAccount, and CheckingAccount with initial balances of f20,000 each and annual interest rates of 2% for the Account and CheckingAccount objects, and 5% for the SavingsAccount object Invoke their tostring() functions at each withdrawal or deposit.Attempt to overdraw the checking account (give it an overdraft limit of f2000) and deposit above the limit for the savings account (give it a deposit limit of f1000) A sample run is shown here:
Account 1432 has a balance of f20000.00 Checking account 1433 has a balance of f20000.00 Savings account 1434 has a balance of f20000.00
Withdrawing f2000.00 from account 1432 Account 1432 has a balance of f18000.00 Attempting to withdraw f5000.00 from checking account 1433 Checking account 1433 has a balance of f15000.00 Attempting to withdraw f20000.00 from checking account 1433
Checking account 1433 has a balance of f15000.00
Depositing f1000.00 to account 1432 Account 1432 has a balance of f19000.00 Attempting to deposit f500.00 to savings account 1434 Savings account 1434 has a balance of f20500.00 Attempting to deposit f10000.00 to savings account 1434 Failed: deposit will exceed limit of f1000.00 for this savings account Savings account 1434 has a balance of 20500.00
