Payroll System Using Inheritance and Polymorphism You need to implement the following harder file and classes.

1. Define the following constants in a header file called Employee.h

• FACULTY_MONTHLY_SALARY = 5000.00
• STAFF_MONTHLY_HOURS_WORKED = 160

2. Implement an abstract class Employee with the following requirements:

• Attributes
• last name (String)
• first name (String)
• ID number (String)
• Default argument constructor and argument constructors.
• Public methods
• putData that displays the following information: ID Employee number :_________ Employee name: __________
• pure virtual method monthlyEarning that returns the monthly earning.

3. Implement a class called Staff extending from the class Employee with the following requirements:

• Attribute
• Hourly rate
• Default argument and argument contructors
• Public methods
• get and set
• The method monthlyEarning returns monthly salary (hourly rate times 160)
• putData that displays the following information: ID Employee number :_________ Employee name: __________ Full Time Monthly Salary: _________

4. Implement a class Education with the following requirements:

• Attributes
• Degree (MS or PhD ) String type
• Major (Engineering, Chemistry, English, etc ... ) String type
• Research (number of researches)
• Default argument and argument constructors.
• Public methods
• get and set

Implement a class Faculty extending from the class Employee with the following requirements:

• Attributes
• Level (use enum statement) "AS": assistant professor "AO": associate professor "FU": professor
• Education object
• Default argument and argument constructor
• Public methods
• get and set
• The method monthlyEarning returns monthly salary based on the faculty's level. AS - faculty monthly salary AO - 1.2 times faculty monthly salary FU - 1.4 times faculty monthly salary
• putData that displays the following information: ID Employee number :_________ Employee name: __________ XXXXX Professor where XXXXX can be Assistant, Associate or Full Monthly Salary: _________

Implement a class called Partime extending from the class Staff with the following requirements:

• Attributes
• Hours worked per week
• Default argument and argument constructors
• Public methods
• set and get
• The method monthlyEarning returns monthly salary which hourly rate multiplied hours worked per week multiplied four.
• putData that displays the following information: ID Employee number :_________ Employee name: __________ Hours works per month: ______ Monthly Salary: _________

Implement a test driver program that creates an array or a vector of class Employees to store the objects Staff, Faculty, and Partime. Using polymorphism, display the following outputs: a. Employee information using the method putData.

• All employees
• Staff
• Faculty
• Part-time

b. Total monthly salary for all employees.

Use the following data to create Employee objects in your program.

Staff

• Last name: Allen First name: Paita ID: 123 Hourly rate: $50.00
• Last name: Zapata First Name: Steven ID: 456 Hourly rate: $35.00
• Last name:Rios First name:Enrique ID: 789 Hourly rate: $40.00

Faculty

• Last name: Johnson First name: Anne ID: 243 Level: Full Degree: Ph.D Major: Engineering Reseach: 3
• Last name: Bouris First name: William ID: 791 Level: Associate Degree: Ph.D Major: English Reseach: 1
• Last name: Andrade First name: Christopher ID: 623 Level: Assistant Degree: MS Major: Physical Education Research: 0

Part-time

• Last name: Guzman First name: Augusto ID: 455 Hourly rate: $35.00 Hours worked per week: 30
• Last name: Depirro First name: Martin ID: 678 Hourly rate: $30.00 Hours worked per week:15
• Last name: Aldaco First name: Marque ID: 945 Hours worked per week: 35

Runtime output
