If yes, how? If not, Why not possible? A: There is nothing like Virtual Constructor. The Constructor can t be virtual as the constructor is a code which is responsible for creating an instance of a class and it can t be delegated to any other object by virtual keyword means. Q: What is constructor or ctor? A: Constructor creates an object and initializes it. It also creates vtable for virtual functions. It is different from other methods in a class. Q: What about Virtual Destructor? A: Yes there is a Virtual Destructor. A destructor can be virtual as it is possible as at runtime depending on the type of object caller is calling to, proper destructor will be called.))))
