What are virtual classes?

• A// base class(display())
  
  B C// B and C child class of A
  
  D// D inheriting from B and C
  Now when D d// object of d is made and a call to display() method is made C++ compiler gets confused as it does not know whether to call display() from B or C. So if the class A is made virtual then only 1 subobject will be inherited by B and C, so no ambiguity arises
