Design a class named Person and its two subclasses named Student and Employee. Design two more classes; Faculty and Staff and inherit them from Employee. The detail of classes is as under:
A person has a name, email address, phone number and address.
A student has a status (String).
An employee has an office, salary, and date hired
A faculty member has office hours and rank
A staff member has a title.
Create display method in each class.
Also create getter, setter and default constructor in above task.

Question 1
Using C# create a class called shapes, the class is supposed to have attributes length, width and height. There should be methods for calculating the area and the perimeter of a shape. Create classes circle, rectangle and square to inherit from class shapes. The derived classes should override methods in the parent class for them to calculate their own areas and perimeters.
What do you call the technique that inserts an object to a function that can replicate the behavior of the object instead of merging objects with different classes?
A. Polymorphism with an Object
B. Abstraction
C. Inheritance
D. Encapsulation

Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.arrow_forward
