COMP 220 iLab
3 Bank Account Lab Report and Source Code
This lab introduces you to writing a C++ program to implement the
concept of class inheritance using different types of bank accounts as a model.
In this lab, you will create a base class, called CBankAccount, and two
additional classes (each derived from CBankAccount), called CSavingsAccount and
CCheckingAccount. You will then test the operations of each class in function
main() to simulate the transactions of both a checking account and a savings
account.
Deliverables
Submit a single Notepad file containing the source code for all
the files of the lab to the Dropbox for Week 3. Your source code should use
proper indentation and be error free. Be sure that your last name and the lab
number are part of the file name: for example, YourLastName_Lab3.txt.
Each program should include a comment section that includes
(minimally) your name, the lab and exercise number, and a description of what
the program accomplishes. Submit a lab report (a Word document) containing the
following information to the Dropbox for Week 3. Include your name and the lab
or lab-exercise number. Specification: Include a brief description of what the
program accomplishes, including its input, key processes, and output. Test
Plan: Include a brief description of the method you used to confirm that your
program worked properly. If necessary, include a clearly labeled table with
test cases, predicted results, and actual results. Summary and Conclusions:
Includea summary of what the lab demonstrated and any conclusions drawn from
the testing of the lab program. Provide a UML diagram showing the base and the
derived class relationships, access specifiers, data types, and function
arguments. Answers to Lab Questions: Answer any and all of the lab questions
included in the lab steps.
Summary: Write a statement summarizing your predicted and actual
output. Identify and explain any differences.
Conclusions: Write at least one nontrivial paragraph that
explains, in detail, either a significant problem you had and how you solved it
or, if you had no significant problems, something you learned by doing the
exercise.
Each lab exercise should have a separate section in the lab-report
document.
Your lab grade is based upon
the formatting of your source code; the use of meaningful
identifiers; the extent of internal documentation; the degree to which an
exercises’ specifications are met; and the completeness of your lab report.
i L A B S T E P S
STEP 1: Create the Multifile Project and the Main (Base) Class
Create a new project that consists of the base class BankAccount.
The BankAccount class should contain, at minimum, the following
members.
It should contain data members to store a bank customer’s balance
and account number. These should be of different and appropriate data types. It
should have function members that do the following: set the account number;
return the account number; return the account balance; deposit money into the
account; and withdraw money from the account.
STEP 2: Create the CheckingAccount Class Derived From the
BankAccount Class
The class CheckingAccount should contain, at a minimum, the
following members.
It should contain a data member to keep track of the number of
withdrawal transactions made on the account. Whenever a withdrawal is made,
this number should be incremented. Override the base class, withdraw-money
function, and add the capability to deduct transaction fees from an account
using the following guidelines. The checking account is allowed three free
transactions. For each successful withdrawal transaction past the three free
transactions, there will be a service fee of 50 cents per transaction. The
service fee should be deducted from the account balance at the time the
transaction is made. If there are insufficient funds in the account balance to
cover the withdrawal plus the service fee, the withdrawal should be denied. The
function should return a value to indicate whether the transaction succeeded or
failed. Transaction fees should be deducted only from successful transactions,
but the transaction count should be incremented in either case.
STEP 3: Create the SavingsingAccount Class Derived From the
BankAccount Class
The class CheckingAccount should contain, at a minimum, the
following members.
It should contain a data member to hold the daily interest rate.
The daily interest rate can be calculated from a yearly interest rate by
dividing the annual rate by 365. It should contain a data member to keep track
of the number of days since the last transaction or balance inquiry. This
should be updated using a random-number generator (reference Lab 1) that will
return a value representing the number of days between 0 and 7, inclusive. We
will assume that this bank is open every day of the year. It should contain a
data member to hold the interest earned since the last transaction or balance
inquiry. It should contain a function member to set the annual interest rate.
Utilize the base-class functions for both withdrawal and deposit operations for
the savings account. Override the base-class-balance inquiry function to add
calculating and adding interest to the account based on the daily interest
rate, the current balance of the account, and the number of days since the last
balance inquiry. This should be called only when a balance inquiry is made, not
when a deposit or withdrawal transaction or an account number inquiry is made.
If there are insufficient funds in the account balance to cover a withdrawal,
the withdrawal should be denied. The number of days since the last transaction
or balance inquiry and the interest calculations should still be made. A value
should be returned to indicate whether a withdrawal transaction succeeded or
failed. It should contain a function member to return the interest earned since
the last transaction or balance inquiry. It should contain a function member to
return the number of days since the last transaction or balance inquiry.
STEP 4: Test Program Operation
All data-input and data-display operations (cin and cout) should
be done in the function main() test program. The test program should create one
checking account and one savings account with initial balances of $100 each
using the functions defined in the class definitions. The test program should
also assign a unique, five-digit account number to each account and assign an
annual interest rate of 3% for the savings account. The test program should
then display a menu that allows the user to select which option is to be
performed on which account, including the following. Make a deposit and specify
the amount to a selected or an entered account. Make a withdrawal and specify
the amount to a selected or an entered account. Return the balance of a
selected or an entered account. For deposit transactions, withdrawal
transactions, and balance inquiries, the updated balance and any fees charged
or interest earned should also be displayed. For the savings account, the
number of days since last transaction should be displayed. Exit the program.
Each account operation should display the account number and the account type.
Lab Questions
Please answer all the lab questions in the text file that is to be
turned into the Dropbox. You are not required to copy the question text into
your document, but all answers should be listed with the question number they
answer.
Were any base-class functions called or overloaded in either of
the derived classes? If so, list which class and which function, and explain
why they were either called or overloaded. Were any derived-class functions not
explicitly called by the test program? If so, list which class and function,
and explain why this was done. Which access attribute was used for each of the
classes derived from the base class? Why was this access attribute chosen?
