Examine the following code snippet. class Shape { public: Shape(); Shape(double new_height, double new_width); void set_height(double new_height); virtual void set_width(double new_width); double get_height const; double get_width const; private: double height; double width; }; void Shape::set_width(double new_width) { width = new_width; } class Rectangle : public Shape { public: Rectangle(); Rectangle(double new_length); Rectangle(double new_height, double new_width, double new_length); void set_width(double new_width); void set_length(double new_length); void print_data const; private: double length; }; void Rectangle::set_width(double new_width) { Shape::set_width(new_width 2); } class Square : public Shape { public: SquareO; Square(double new_height, double new_width, double new_length); void set_width(double new_width); void set_length(double new_length); void print_data const; private: double length; }; void Square::set_width double new_width) { Shape::set_width(new_width * 3); } int maino { Shape s = new Square; s->set_width(300.00); return 0; } Which set_width function is called? The set_width function defined in the Shape class The set_width function defined in the Rectangle class The set_width function defined in the Square class None of the above due to a compile-time error
