Extracted text: Absolute Requirements The Account class must be an abstract class with two pure virtual functions, closeMonth and accountString. The Savings and Checking classes must be subclasses of Account The bank must handle at least 10 accounts simultaneously with account numbers 1-9. Do not duplicate the balance or ID fields in the subclasses The balance, withdrawal and deposit manipulation must use the methods in the base class Account. Each action must display appropriate messages indicating that the action was completed. The closeMonth and accountString functions must be called polymorphically. This means, they are called for each account without checking to see what kind of account it is being called on. An implication of the last point is that there will be a single array of Account objects, some of which are Checking accounts and some of which are Savings accounts. An example bank2.txt file and sample output are attached to the assignment.


Extracted text: Inheritance and Polymorphism Based on the UML diagram from Lab #6, implement the three classes, Account, Checking, and Savings. Then implement a main program that reads commands from bank2.txt and carries out the commands using objects of these classes. New Commands Checking account initialBalance minimumBalance monthlyFee Savings account initialBalance minimumBalance annuallnterestRate Deposit account amount Withdraw account amount Balance account Close Report In the above commands, account is an integer between 1 and 9. All other arguments are doubles. The close command performs the end of month functions for every existing account. The only output it produces is an "End of month processing complete" message. Note that Savings accounts have an annual interest rate, but at the end of the month only the monthly interest rate should be added. The annual interest rate is specified as a percentage, so a 7.5% interest rate is indicated as 7.5 in the Savings command. The Report command lists all existing accounts and their balances, like - Checking account #1 has a balance of $402.25 Savings account #2 has a balance of $53576.65 Tasks 1. Modify the Account class. 2. Implement and test your new subclasses. 3. Modify your main function from Lab 5 to handle the new commands. 4. Test your program thoroughly. The instructor will use a different bank2.txt file to evaluate your program. 5. Submit the working classes and main program via the assignment.
