I've gone through several books they explain Upcasting as
Base class pointer pointing to Drived class Object
this definition is correct.
Downcasting:
Drived class pointer pointing to base class object..
i got a bit confused.....not having crystal clear image in my mind.....
if the above definition is correct... whats wrong with the below code
class Shape {
public:
virtual ~Shape() {}
};
class Circle: public Shape {
public:
~Circle() {}
};
int main()
{
//why this can't work ...........according to definition....
// Circle* c = dynamic_cast<Shape*>(new Shape);
//why this
Shape* s = new Shape;
Circle* c = dynamic_cast<Circle*>(s);
return 0;
}
I know that downcasting is performed between polymorphic types
. I m bit confused with its definition and implementation... please give me the solid concept
