Source Code

CIRCLE

#include "Circle.hpp" Circle::Circle() { radius = 1.0; } Circle::Circle(double rad) // parametrized constructor { radius = rad; } // getters double Circle::getRadius() {return radius;} // setters void Circle::setRadius(double newrad) {radius = newrad;} // methods double Circle::area() {return PI*radius*radius;} double Circle::circunference() {return 2*PI*radius;} double Circle::diameter() {return 2*radius;} bool Circle::compareWithRect(Rectangle rect) { return rect.area() == area(); }

RECTANGLE

#include "rectangle.hpp" #include Rectangle::Rectangle() { length = 1.0; width = 1.0; } Rectangle::Rectangle(double l, double w) { length = l; width = w; } // getters double Rectangle::getLength() {return length;} double Rectangle::getWidth() {return width;} // setters void Rectangle::setLength(double newlength) {length = newlength;} void Rectangle::setWidth(double newwidth) {width = newwidth;} // methods double Rectangle::area() {return length*width;} double Rectangle::diagonal() {return sqrt(pow(length, 2) + pow(width, 2));} double Rectangle::perimeter() {return 2*(length + width);}
