Question

Objective
- Create a base class named Circle with data members and functions related to circles and a derived class named Cylinder with data members and functions related to cylinders.
- There are no extra .h or .cpp needed for this assignment.
Create a program named LastnameFirstname21.cpp, that does the following:
1. Note: There is no user input for this program.
2. Define a symbolic constant named PI with the value 3.1415926. Use this symbolic constant when dealing with calculations involving PI.
3. Define a base class named Circle for storing the radius and calculating the area of a circle.
4. Circle class contains the following:
  1. 1 protected double data member for the radius.
  2. 1 default constructor that creates a circle with radius 1.
  3. 1 overloaded constructor with a parameter that creates a circle with a given radius.
  4. 1 accessor function named getRadius for the radius.
  5. 1 mutator function named setRadius for the radius.
  6. 1 member function named area that calculates and returns the area of the circle.
    - area = πr²
  7. Any member functions that do NOT modify the radius data member use the const keyword to ensure those functions do not accidentally modify the data member.
  8. Any member functions that do modify the radius data member implements the following error correction:
    - If the radius will be 0, make it 1 instead.
    - If the radius will be negative, make it positive instead.
5. Define a derived class named Cylinder (which inherits all data members and member functions of class Circle) for storing the radius (in base class Circle) and height and calculating the area (surface area) and volume of a cylinder.
6. Cylinder class contains the following:
  1. 1 private double data member for the height.
  2. 1 constructor that creates a Cylinder given a radius and height and uses the inherited Circle constructor to initialize the radius data member.
  3. 1 accessor function named getHeight for the height.
  4. 1 mutator function named setHeight for the height.
  5. 1 member function named area that calculates and returns the surface area of the cylinder.
    - surface area of a cylinder = 2πrh + 2πr²
    - This member function will override the inherited member function from the Circle class.
  6. 1 member function named volume that calculates and returns the volume of the cylinder
    - volume of a cylinder = πr²h
  7. Any member functions that do NOT modify the height data member use the const keyword to ensure those functions do not accidentally modify the data member.
  8. Any member functions that do modify the height data member implements the following error correction:
    - If the height will be 0, make it 1 instead.
    - If the height will be negative, make it positive instead.
7. Use my main() to test your classes to get the same output shown below: https://laulima.hawaii.edu/x/ndIl9Y
8. Be sure to have a program description at the top and in-line comments.

Example Output
% make
% ./program
Test Circle class default constructor and area() function:
Circle circle1: radius = 1
area 3.14159
Test Circle class constructor with radius (-10):
Circle circle2: radius = 10
Test set method, set circle2 to radius -5...
radius = 5
area = 78.5398
Test Cylinder class given radius (20) and height (-30):
Cylinder cylinder1: radius = 20; height
= 30
surface area = 6283.19
volume = 37699.1
Test set method, set cylinder1 to radius (0) and height (0)...
radius= 1; height
= 1
surface area = 12.5664
volume = 3.14159
