Issue with line class polymorphism

[sturk]

Hi, I need help in getting my code to output the required text as shown below.
Problem is in my class line constructor, I'm stuck at the moment on how to achieve the output as shown. If anyone could help, I would really appreciate it. Thanks.

Output required:
1 //Ok
Shape() Polygon() Line() //Ok
4 //Ok
Line(Polygon(Shape(Color(0,0,0)) Point(0,0) Point(0,0))) // Not ok

class Point
{
private:
   int x;
   int y;

public:
   Point() : x(0), y(0) {}
   Point(int x, int y) : x(x), y(y) {}

public:
 
};

class Line : public Point 
{
private:
   Point p1;
   Point p2;
	
public:
   Line() :  p1(Point(0, 0)), p2(Point(0, 0)) {}

};

int main() {

	cout << "1" << endl;
	Line l; 
	cout << "Shape() Polygon() Line() "<< endl;
        
        cout << "4" << endl;
	cout << l;
	cout << endl;

No, your problem is that you haven't overloaded the << operator for objects of class Line, so your code won't know what to do when it sees
cout << l;

Hi lastchance, I'm confused becoz of this-> Polygon(Shape(Color(0,0,0)). So for this do I explicitly type out Polygon(Shape(Color(0,0,0)) in my cout? Thanks btw.

Hi @playpro, I'm confused becoz I don't see
this-> Polygon(Shape(Color(0,0,0));
anywhere in your code.
