Pure Abstract Base Class Project
Define a pure abstract base class called BasicShape. The BasicShape class should have the following members:
Private Member Variable:
area: A double used to hold the shape’s area.
Public Member Functions:
get Area: This function should return the value in the member variable area.
calcArea: This function should be a pure virtual function.
Next, define a class named Circle. It should be derived from the BasicShape class. It should have the following members:
Private Member Variables:
centerX: a long integer used to hold the x coordinate of the circle’s center
centerY: a long integer used to hold the y coordinate of the circle’s center radius: a double used to hold the circle’s radius Public Member Functions:
constructor: accepts values for centerX. centerY, and radius. Should call the overridden calcArea function described below.
getCenterX: returns the value in centerX
getCenterY: returns the value in centerY
calcArea: calculates the area of the circle (area = 3.14159 * radius * radius) and stores the result in the inherited member area.
Next, define a class named Rectangle. It should be derived from the BasicShape class. It should have the following members:
Private Member Variables:
width: a long integer used to hold the width of the rectangle
length: a long integer used to hold the length of the rectangle
Public Member Functions:
constructor: accepts values for width and length. Should call the overridden
calcArea function described below.
getWidth: returns the value in width.
get Length: returns the value in length.
calcArea: calculates the area of the rectangle (area = length * width) and stores the result in the inherited member area.
After you have created these classes, create a driver

1. Employee and ProductionWorker Classes
Write an Employee class that keeps data attributes for the following pieces of information:
Employee name
Employee number
Next, write a class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information:
Shift number (an integer, such as 1, 2, or 3)
Hourly pay rate
The workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write the appropriate accessor and mutator methods for each class. Once you have written the classes, write a program that creates an object of the ProductionWorker class and prompts the user to enter data for each of the object’s data attributes. Store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen.
