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.

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.

on the account. Whenever a withdrawal is made, this number should be incremented. Override
