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:

getArea - 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.

getLength 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 program that defines a Circle object and a Rectangle object. Demonstrate that each object properly calculates and reports its area
