In Interface, all the member functions are abstract implicitly
so it is imp. to define all fn. declared inside Interface.
Moreover, we cann't define a fn. or we cann't declare any
member variable in an Interface. Also, we cann't declare or
define any non-abstract method in Interface.
In Abstract class, we can declare an abstract method as well
as we can also define a non-abstract method. We can also
declare a variable member in abstract class.
In both the condition, declared abstract method is
implemented out side the class i.e in derived class which
inherits Interface/Abstract class, whatever you have used.
