Program SpecificationUsing python, design a class 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 MUST use exception handling. You can choose how to implement the exception handling. Start your program with a welcome message Make sure…
People in School Objective: At the end of the activity, the students should be able to: Create a program that exhibits inheritance. Procedure: Write a simple information system that will store and display the complete information of a student, faculty, or employee. Create four (4) no-modifier classes named Person, Student, Faculty, and Employee. Create a public class named CollegeList. This class shall contain the main method. Refer to the UML Class Diagram for the names of the variables and methods. The (-) symbol represents private variables, while (+) represents public method. This should be the sequence of the program upon execution: Prompt the user to select among Employee, Faculty, or Student, by pressing E, F, or S. Ask the user to type the name and contact For Employee, ask the user to type the employee's monthly salary and the department where he/she belongs to (Ex. Registrar). Then, display name, contact number, salary, and For Faculty, ask the user to press Y if…

B. Pet Class Using Python Program, Write a class named Pet, which should have the following data attributes: • _ _name (for the name of a pet) •__animal_type (for the type of animal that a pet is. Example values are 'Dog', 'Cat', and `Bird')' __age (for the pet's age) init The Pet class should have an method that creates these attributes. It should also have the following methods: set_name() This method assigns a value to the __name field. set_animal_type() This method assigns a value to the __animal_type field. • set_age() This method assigns a value to the • get_name() This method returns the value of the get_animal_type() This method returns the value of the __animal_type field. • get_age() This method returns the value of the _age field. Once you have written the class, write a program that creates an object of the class and prompts the user to enter the name, type, and age of his or her pet. This data should be stored as the object's attributes. Use the object's accessor methods…
Classes: Write a Person class that has these attributes: person_ID, first and last names, and age Default and overloaded constructors Accessors and mutators equals method toString method (make this virtual if C++, don't forget to prep the class for polymorphism) Inheritance: Create a child class to Person called Student: Attributes: GPA and status (freshman, sophomore, junior, senior, graduate, graduated). Make sure you have appropriate accessor/mutator methods Create another child class to represent Faculty. This class will have faculty rank and length of service as attributes along with an office location. Again, add methods as needed. Application Create an application that displays a menu that allows users to add students or faculty, or print either one or exit. Deliverable: Submit your source code and classes on Github (you will be supplied an account) You will also submit a Word document and your code on Canvas. In the document you iwll write a summary of your design…
