PersonData and CustomerData classes
Design a class named PersonData with the following member variables:
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:
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 mailingList, or false if the customer does not wish to be on a mailingList.
Write appropriate accessor and mutator functions for these member variables.
Demonstrate an object of the CustomerData class in a simple program. Must be on one source.cpp file.
