A virtual function is basically a like normal function but
we can override the function in the derived classes.
Now when we want to access like (fn)

Base * bptr = new Derived();
bptr->fn(); then function of the derived class will be
called only if the function is marked as virtual in the
base class.

i.e the virtual keywork tells to use the function of the
class to which it is pointing to and not to the Base class.
This is called runtime polymorphism.
