The implementation of GeometricObject and Circle is provided below. You are asked to supply the Ring class by reverse-engineering the hierarchy shown above. r1 The Ring class represents a solid circular band with an outer and inner radius (say rl and r2 respectively). See figure on the right. Only the segment enclosed between rl and r2 is considered part of the ring. r2 Design Specifications 1. The Ring class is a public descendant of the Circle class. 2. It enhances the Circle definition by including a second radius used to set the inner face of the circular figure Main #include "Geometricobject.h" #include "Circle.h" #include "Ring.h" int main() { cout #include #include #include #include using namespace std; //Declaration section class Geometricobject { private: string color; //utility routine to force text to proper cap format string properCap(string original); //list of valid colors - children may reduce it but not enlarge it vector validColors{ "White", "Red", "Blue" }; public: const double PI = 3.1415; //Accessors -Mutators void setColor(string c); string getColor() { return color; } //Constructor Geometricobject(string c = "Blue") { setColor(); } //User-defined functions virtual string toString(); //Descendants MUST implement it virtual double calculateArea() = 0; //PURE VIRTUAL virtual double calculatePerimeter() = 0; //PURE VIRTUAL }; // IMPLEMENTATION SECTION string Geometricobject::toString() { stringstream sout; sout radius = abs(radius); } // constructors Circle(double radiusValue = 0, string colorValue = "Red") : Geometricobject(colorValue) { setRadius (radiusValue); } //programmer-defined methods string toString() override; double calculateArea() override { return PI * radius * radius; } double calculatePerimeter() override { return 2 * PI * radius; } }; // IMPLEMENTATION string Circle::toString() { stringstream sout; sout #include #include #include #include using namespace std; //Declaration section class Geometricobject { private: string color; //utility routine to force text to proper cap format string properCap(string original); //list of valid colors - children may reduce it but not enlarge it vector validColors{ "White", "Red", "Blue" }; public: const double PI = 3.1415; //Accessors -Mutators void setColor(string c); string getColor() { return color; } //Constructor Geometricobject(string c = "Blue") { setColor(); } //User-defined functions virtual string toString(); //Descendants MUST implement it virtual double calculateArea() = 0; //PURE VIRTUAL virtual double calculatePerimeter() = 0; //PURE VIRTUAL }; // IMPLEMENTATION SECTION string Geometricobject::toString() { stringstream sout; sout radius = abs(radius); } // constructors Circle(double radiusValue = 0, string colorValue = "Red") : Geometricobject(colorValue) { setRadius (radiusValue); } //programmer-defined methods string toString() override; double calculateArea() override { return PI * radius * radius; } double calculatePerimeter() override { return 2 * PI * radius; } }; // IMPLEMENTATION string Circle::toString() { stringstream sout; sout
