Question

Design a class for python named PersonData with the following member variables:

• lastName
• firstName
• address
• city
• state
• zip
• phone

Write the appropriate accessor and mutator functions for these member variables. Next, design a class named CustomerData , which is derived from the PersonData class. The CustomerData class should have the following member variables:

• customerNumber
• mailingList

The customerNumber variable will be used to hold a unique integer for each customer. The mailingList variable should be a bool . It will be set to true if the customer wishes to be on a mailing list, or false if the customer does not wish to be on a mail-ing list. Write appropriate accessor and mutator functions for these member variables.

Next write a program which demonstrates an object of the CustomerData class in a program. Your program MUSTuse exception handling. You can choose how to implement the exception handling.

Tips for full credit

• Start your program with a welcome message
• Make sure to include comments in your program
• Use good variable names. A good variable name is one which describes what is stored in it. Subtotal is a good variable name while x is a weak one.
• Use correct indentation
• Organize your non object oriented code into a main function
• User inheritance
• Use exception handling
• Use more than two methods in your program which demonstrates the class you created
