Answer Posted / rck
5)A.
Virtual Base Class is the concept comes under multipath inheritance.If a class (for ex:class D) dervied from two base classes(class B and class C) which are already derived from a single base class(class A) is called multipath inheritance.
Now the derived class (D) will acquire properties of base class (A) form both classes(B and C) thus leads to ambiguity.In order to avoid that we declare Virtual infront of the base class thus only one copy of the class is derived to the derived class (D).
