Polymorphism and Inheritance

Shape.h

class Shape {

           string color;

           bool filled;

public:

           Shape();

           Shape(string, bool);

           string getColor();

           bool isFilled();

           void setColor(string);

           void setFilled(bool);

           string toString();

//virtual string toString();

};

Rectangle.h

class Rectangle : public Shape {

           double length;

           double width;

public:

           Rectangle();

           Rectangle(double, double);

           Rectangle(double, double, string, bool);

           double getLength();

           double getWidth();

           void setLength(double);

           void setWidth(double);

           double getArea();

           double getPerimeter();

printShape() function prototypes:

void printShape(Shape); or

void printShape(Shape &);

^^test which works correctly

Make a Rectangle class and a Triangle class that extend Shapeclass

^^not sure how to do this

the main that has to be used

int main() {

Shape s;

Rectangle r(5,6, \"red\", true);

Triangle t(6, 10, \"blue\", true);

printShape(s);

Shape s1(\"blue\", false);

printShape(s1);

//add virtual and pass the object by reference

printShape(r);

printShape(t);

return 0;

}

the instances need to be created and printShape() method needsto be called

triangle formula used is =1/2base*height
