Project 4 Design

Due Date

Objective

The objective of this assignment is to make sure that you begin thinking about your project in a serious way early. This will not only give you experience doing design work, but will help you anticipate the number of hours that you'll need to set aside to be able to complete the project.

The Assignment

Part 1 - Designing Inheritance

Write the header files for the 4 Customer classes in the hierarchy. Be sure to include at least one virtual or pure virtual function in the hierarchy. Also be sure to include all common data and methods in the Customer class and all derived-class specific data and methods in the derived classes. Include appropriate header comments with pre and post conditions.

Part 2 - Testing System

Create 3 testing command files that you will use to test your system. They should each focus on one of the derived-classes in the hierarchy. Be sure that these command files thoroughly test your derived-classes.

Grading

You p4design.txt file will count as 10% of your project 4 grade (part of the Correctness). If this file is not submitted by its due date, or if you submit a new version after its due date, you will lose all 10 points.

Your p4design.txt file will be compared to the header file or files that you submit when Project 4 is due. Minor changes to the design are allowed. A minor change might be the addition of another function or two or changing the way in which one or two parameters are passed.

If there are major changes between the design document and the header files that are part of the final project, you will lose 5 points. This would indicate that you didn't give sufficient thought to your design before beginning the implementation.

A template for your design document, p4design.txt, is provided in Ms. Wortman's public directory. Copy that file

/afs/umbc.edu/users/d/a/dana3/pub/CMSC202/p4/p4design.txt to your local directory and fill in the necessary information. Submit your modified p4design.txt file to complete this assignment.
