Define a pure abstract base class called BasicShape.

*Pre-requisite

• 15.6 Polymorphism and Virtual Member Functions
• 15.7 Abstract Base Classes and Pure Virtual Functions

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 must 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 circles center.
• centerY, a long integer used to hold the y coordinate of the circles center.
• radius, a double used to hold the circle's radius.

Public Member Functions:

• constructoraccepts values for centerX, centerY, and radius. Should call the overridden calcArea function described below.
• getCenterXreturns the value in centerX.
• getCenterYreturns the value in centerY.
• calcAreacalculates 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:

• constructoraccepts values for width and length. Should call the overridden calcArea function described below.
• getWidthreturns the value in width.
• getLengthreturns the value in length.
• calcAreacalculates the area of the rectangle (area = length * width) and stores the result in the inherited member area.

After you have created these classes, use the provided driver program below that defines a Circle object and a Rectangle object. Demonstrate that each object properly calculates and reports its area.

Sample Test Run

Submit

1. source code in text
