I am typecasting object from derived class to base class. As it has to slice object and create the base object , why copy constructor of base class is called instead of move constructor? Object is temporary so it should call move constructor, right?

Answer 1

The instance `d` is an lvalue and not temporary, why should the move constructor be called?

Answer 2

Yes.

Answer 3

My bad
Casted object is rvalue...right ? Not the d..so should be doing move(d) to have move constructor call
