Program To Create Circle Construction Assignment Solution.

Instructions

Objective

Write a C++ assignment to create a program for circle construction. The task involves implementing a program in C++ that allows the user to construct circles. The program should prompt the user to input the radius and then calculate the area and circumference of the circle. It should display these values to the user. Utilize appropriate C++ concepts such as classes and functions to structure your code effectively. This assignment aims to test your understanding of object-oriented programming and your ability to apply mathematical formulas in C++. Ensure that your code is well-documented and follows best coding practices.

#include 
// Define the value of PI
#define PI 3.14159265358979323846
class Circle {
 private:
 double radius;
 public:
 // Constructor with no arguments
 Circle() {
 // Initializes the radius to 2.0
 radius = 2.0;
 }
 // Constrcutor that accepts the radius as argument
 Circle(double r) {
 radius = r;
 }
 // Getter and Setter for radius
 double getRadius() {
 return radius;
 }
 void setRadius(double r) {
 radius = r;
 }
 // method to calculate area
 double getArea() {
 // returns pi*radius^2
 return PI*getRadius()*getRadius();
 }
 // method to print the area
 void printArea() {
 // Calculate area
 double area = getArea();
 std::cout << "The area of the Circle with radius " << getRadius() << " (u) is: " << getArea() << " (u^2)" << std::endl;
 }
