While solving diamond of death problem how many VTABLE will be created?

[Ferdinend]

class A {};
class B : virtual public A {};
class C : virtual public A {};
class D : public B, public C {};


In this how many VTABLE will be created? And for which classes this VTABLE will be created?

This sounds like a homework question.

Assuming that is is homework, the hint is that a VTBL contains the addresses of the virtual functions either declared or inherited by the class.

You should be able to get your answer from this.
