Homework 4
Due Monday, April 22

1. (15 pts) The class Maze that we created in lectures 7, 8 and 9 has a memory leak (in one of the functions that has been implemented). Find it and explain how to fix it.
2. (20 pts) Write the declaration for three classes: BankAccount, CheckingAccount, and SavingsAccount. All three clases should have appropriate constructors. BankAccount should have an account number, an id for the account holder, and an account balance. Provide member functions for depositing, withdrawing, and finding out the balance and the account number. The classes CheckingAccount and SavingsAccount should each be derived from the BankAccount class. The CheckingAccount class should inherit all of BankAccount's members, and should have additional data members for minimum balance and service fee. Provide access functions (get and set) for these data members, and a function for charging the monthly fee to the account. The SavingsAccount class should also inherit all of BankAccounts's members, and should have an additional data member for the interest rate. Provide access functions (get and set) for this data member, and a function for adding the accrued interest to the account. Please note that I am not asking you to implement these classes - just write the declarations.
3. (15 pts) April 29 (the due date for your first project) is drawing near. By April 22, you should have at the very least implemented reading of the data files, and building the data structures. Preferably you will also have implemented a couple of the functions for generating the lists of relatives. Write down a few lines that tell me what the status of your program is. If you are working with another person, also tell me how you think the collaboration is going.
