Proper working code
Consider the following class definition:
class circle { public: void print() const;
void setRadius(double);
void setCenter(double, double);
void getCenter(double&, double&);
double getRadius();
double area();
circle();
circle(double, double, double);
double, double);
private: double xCoordinate;
double yCoordinate;
double radius; }
class cylinder: public circle { public: void print() const;
void setHeight(double);
double getHeight();
double volume();
double area();
cylinder();
cylinder(double, double, private: double height; }
Suppose that you have the declaration: cylinder newCylinder;
Write the definitions of the member functions of the classes circle and cylinder. Identify the member functions of the class cylinder that overrides the member functions of the class circle
