Virtual, as the name implies, is something that exists in
effect but not in reality. The concept of virtual function
is the same as a function, but it does not really exist
although it appears in needed places in a program. The
object-oriented programming language C++ implements the
concept of virtual function as a simple member function,
like all member functions of the class.
Need for Virtual Function:
The vital reason for having a virtual function is to
implement a different functionality in the derived class.
For example: a Make function in a class Vehicle may have to
make a Vehicle with red color. A class called FourWheeler,
derived or inherited from Vehicle, may have to use a blue
background and 4 tires as wheels. For this scenario, the
Make function for FourWheeler should now have a different
functionality from the one at the class called Vehicle.
This concept is called Virtual Function.
