Whether Virtual Function is available or not, derived class pointer is not required at all. When base class pointer is created, both the members from base and derived can accessible from it.

Because its top-down approach.

@Souradip.
I am totally agree with you. Because it is not at all possible that the base class holds the contents of derived class.

Base class has capability to create pointer. Derived class is derived from base class only so it is also has access that pointer.

Because derived class does not have detailed about its based class.

Yeah sure its not necessary to do this but we can assign base class object's address to a derived class pointer by typecasting.

I agree with @Sneha kuwar because derive class does not have any knowledge about its base class.

Hi guys. But using static_cast<> we can assign base class pointer to derived class pointer.
