Question

Please separate this code with different header files thank you.

#include<iostream>
//bismark

using namespace std;
public:
   class Circle {

   private double radius;
   private char color;
   private boolean filled;

   public Circle(double radius, char color, boolean filled) {
       super();
       this.radius = radius;
       this.color = color;
       this.filled = filled;
   }

   public Circle() {
       super();
       this.radius = 0;
       this.color = 'W';
       this.filled = false;
   }

   public Circle(double radius) {
       super();
       this.radius = radius;
       this.color = 'W';
       this.filled = false;
   }

   public double getRadius() {
       return radius;
   }
   public void setRadius(double radius) {
       this.radius = radius;
   }
   public char getColor() {
       return color;
   }
   public void setColor(char color) {
       this.color = color;
   }
   public boolean isFilled() {
       return filled;
   }
   public void setFilled(boolean filled) {
       this.filled = filled;
   }

   public double getCircumference(double r)
   {

       return 2 * 3.14*r;

   }

   public double getArea(double r)
   {
       return 3.14*r*r;
   }

}

circle.h

class Circle
{
private:
double radius;
char color;
bool filled;

public:
//constructors
Circle(double radius, char color, bool filled);
Circle();
Circle(double radius);
//getter and setter methods
double getRadius();
void setRadius(double radius);
char getColor();
void setColor(char color);
bool isFilled();
void setFilled(bool filled);
//helper methods
double getCircumference(double r);
double getArea(double r);
};

Circle.cpp

#include "circle.h"

Circle::Circle(double radius, char color, bool filled) //parametrized constructor
{
this->radius = radius;
this->color = color;
this->filled = filled;
}
Circle::Circle() //default constructor
{
this->radius = 0;
this->color = 'W';
this->filled = false;
}
Circle::Circle(double radius) //parametrized constructor
{
this->radius = radius;
this->color = 'W';
this->filled = false;
}
//getter and setter methods
double Circle::getRadius()
{
return radius;
}
void Circle::setRadius(double radius)
{
this->radius = radius;
}
char Circle::getColor()
{
return color;
}
void Circle::setColor(char color)
{
this->color = color;
}
bool Circle::isFilled()
{
return filled;
}
void Circle::setFilled(bool filled)
{
this->filled = filled;
}
//helper methods
double Circle::getCircumference(double r)
{
return 2 * 3.14*r;
}
double Circle::getArea(double r)
{
return 3.14*r*r;
}

mainTest.cpp

#include <iostream>
#include "circle.cpp"
using namespace std;

int main()
{
//testing the class Circle
Circle c(10);
cout << "Circumference: " << c.getCircumference(c.getRadius()) << endl;
cout << "Area: " << c.getArea(c.getRadius()) << endl;
return 0;
}
