Answer / p.kumarasamy,be(cse)
C++ virtual function is a member function of a class, whose
functionality can be over-ridden in its derived classes. The
whole function body can be replaced with a new set of
implementation in the derived class. The concept of c++
virtual functions is different from C++ Function overloading.
