? Analyze the requirements of the project carefully and divide the tasks among group

members to demonstrate an efficient teamwork. You should assign one member as a group

leader.

? The project should be implemented as a multi-file program i.e., using abstraction

methodology.

? You need to submit the following information (See the shared file at OneDrive) about your

group till 27 December, 2020.

o Group Name

o Group members name and ID (mention the group leader)

Create a class BankAccount to hold at least the following data / information about a bank

account:

? Account balance

? Total number of deposits

? Total number of withdrawals

? Interest rate e.g., annual rate = 0.05

? Service charges per month

The class should have the following member functions:

Constructor To set the required data. It may be parameterized or user’s input.

depositAmount A virtual function used to accept an argument for the amount to

be deposited. It should add the argument (amount) to the account

balance. It should also increment the variable used to track the

number of deposits.

withdrawAmount A virtual function used to accept an argument for the withdraw

amount operation. It should subtract the argument from the

account balance. It should also increment the used to track the

number of withdrawals.

calculateInterest A virtual function which calculates the monthly interest of the

account and then updates the account balance by adding it to the

principal amount.

Note: Use the standard formulas/operations (monthly interest

calculation) to implement this function.

monthlyProcessing A virtual function which calls the calculateInterest function,

subtracts the monthly service charges from the balance, and then

sets the corresponding variables such as no. of withdrawals, no.

of deposits, monthly service charges and so on.

getMonthlyStatistics A member function used to display the monthly statistics of the

account such as deposit, withdrawals, service charges, balance

etc.

Next, create a SavingAccount class which is derived from the generic class BankAccount.

It should at least have one additional data member, i.e., ‘status’ that will be used to show whether

account is active or inactive.

If the balance of a savings account falls below RM 25, it becomes inactive and the account holder

will not be able to perform withdraw operation anymore until the balance is raised above RM 25.

If balance becomes greater than or equal to RM 25, the account will become active again.

The most common member functions of the SavingAccount class are given below.

depositAmount A function which first checks whether the account is active/inactive before

making a deposit. If inactive and the deposit brings the balance above RM

25, the account will become active again. The deposit will then be made

by calling the base class version of the function.

withdrawAmount A function which first checks whether the account is active/inactive before

making a withdrawal. If active, the withdrawal will be made by calling the

base class version of the function.

monthlyProcessing

This function first checks the no. of withdrawals before calling the base

class version of this function. If the number of withdrawals are more than

4, a service charge of RM 1 for each withdrawal greater than or equal to

RM 4 is added to the base class variable that holds the monthly service

charges. Note: check the account balance after applying the service charge.

If the balance become lower than RM 25, the account becomes inactive

again.

Next step is to design a CheckingAccount class. It is also derived from the generic account

class and should at least have the following member functions.

withdrawAmount This function first determines whether a withdrawal request will cause the

balance to go below RM 0. If it falls below RM 0, a service charge of RM

15 will be deducted from the account, and the withdrawal will not be made.

If there is not enough amount to deduct the service charges, the balance

will become negative accordingly.

monthlyProcessing This function applies a monthly fee of RM 5 plus RM 0.10 per withdrawal

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

Input Validations: Apply input validations wherever appropriate such as input data format for

account number and title, and other validation checks applied in a practical banking system.

Assume the account number is a 6-digit integer value (324561).

Implement the above functionality using abstraction methodology. This project requires to

simulate one Saving and one Checking account, however, simulating multiple accounts (may be

up to 5) is encouraged. If you simulate multiple accounts, highlight it in your report and the

presentation file. You may need to add more member variables and functions than those listed

above. Your application should at least provide the following functionality (a sample run):

Bank Account System

1. Saving Account Number

2. Saving Account Title

3. Checking Account Number

4. Checking Account Title

5. Deposit in a Saving Account

6. Deposit in a Checking Account

7. Withdraw from Saving Account

8. Withdraw from Checking Account

9. Update and Display Account Statistics

10. Exit

Upon selecting the desired option in the above menu, your application should perform the

required functionality.
