14. Bank Accounts

This program should be designed and written by a team of students. Here are some

suggestions:

One or more students may work on a single class.

The requirements of the program should be analyzed so each student is given about

the same work load.

The parameters and return types of each function and class member function should

be decided in advance.

The program will be best implemented as a multi-file program.

Design a generic class to hold the following information about a bank account:

Balance

Number of deposits this month

Number of withdrawals

Annual interest rate

Monthly service charges

The class should have the following member functions:

Constructor : Accepts arguments for the balance and annual interest rate.

deposit : A virtual function that accepts an argument for the amount of the

deposit. The function should add the argument to the account balance.

It should also increment the variable holding the number of deposits.

withdraw : A virtual function that accepts an argument for the amount of the

withdrawal. The function should subtract the argument from the

balance. It should also increment the variable holding the number of

withdrawals.

calcInt : A virtual function that updates the balance by calculating the monthly

interest earned by the account, and adding this interest to the balance.

This is performed by the following formulas:

Monthly Interest Rate = (Annual Interest Rate / 12)

Monthly Interest = Balance * Monthly Interest Rate

Balance = Balance + Monthly Interest

monthlyProc : A virtual function that subtracts the monthly service charges from the

balance, calls the calcInt function, and then sets the variables that

hold the number of withdrawals, number of deposits, and monthly

service charges to zero.

Next, design a savings account class, derived from the generic account class. The savings

account class should have the following additional member:

status (to represent an active or inactive account)

If the balance of a savings account falls below $25, it becomes inactive. (The status

member could be a flag variable.) No more withdrawals may be made until the balance

is raised above $25, at which time the account becomes active again. The savings

account class should have the following member functions:

withdraw : A function that checks to see if the account is inactive before a withdrawal

is made. (No withdrawal will be allowed if the account is not

active.) A withdrawal is then made by calling the base class version of

the function.

deposit : A function that checks to see if the account is inactive before a deposit

is made. If the account is inactive and the deposit brings the balance

above $25, the account becomes active again. The deposit is then

made by calling the base class version of the function.

monthlyProc : Before the base class function is called, this function checks the number

of withdrawals. If the number of withdrawals for the month is

more than 4, a service charge of $1 for each withdrawal above 4 is

added to the base class variable that holds the monthly service charges.

(Dont forget to check the account balance after the service charge

is taken. If the balance falls below $25, the account becomes inactive.)

Next, design a checking account class, also derived from the generic account class. It

should have the following member functions:

withdraw : Before the base class function is called, this function will determine if a

withdrawal (a check written) will cause the balance to go below $0. If

the balance goes below $0, a service charge of $15 will be taken from

the account. (The withdrawal will not be made.) If there isnt enough

in the account to pay the service charge, the balance will become negative

and the customer will owe the negative amount to the bank.

monthlyProc : Before the base class function is called, this function adds the monthly

fee of $5 plus $0.10 per withdrawal (check written) to the base class

variable that holds the monthly service charges.

Write a complete program that demonstrates these classes by asking the user to enter

the amounts of deposits and withdrawals for a savings account and checking account.

The program should display statistics for the month, including beginning balance, total

amount of deposits, total amount of withdrawals, service charges, and ending balance.
