oops concepts are
1.Object
An object is collection of data members and associated
member functions.

2.Class
Class is a data structure which encapsulates data and
member function in a single unit and the member funtions of
the class are used to access member variables.

3.Abstraction
Abstraction is of the process of hidding data.
or
Identifying the important properties of existing modes.

4.Encapsulation
The wrapping up of data and methods in a single unit is
known as encapsulation.

5.Polymorphism
Process of aquiring properties from one object to another
with changes.
or
The same operation can be applied differntly in diffent
objects.
ex:5+2,a+b.

6.Inheritance
Process of aquiring properties from one object to another
without changes.
or
Identifying the important features based on one class to
next class.
