Object oriented programming is a principal of design and development of programs using
modular approach.
Some of object oriented programming languages are JAVA,C++ and C# etc.

Basic concepts/characteristics of OOPs.
1. Objects
2. Classes
3. Data abstraction
4. Data encapsulation
5. Inheritance
6. Overloading
7. Polymorphism
8. Dynamic binding
9. Message passing

Objects:
 Objects are basic building blocks for designing programs.
An object can be defined as an identifiable entity that has data and associated functions.
 Every object has to be given the unique name.
 examples:
An object may represent a person, place or a table of data.
Objects are saved in memory and associated with address.
During execution of program objects will communicate with each other by sending message to
one another.

Object-car
data Color
Opendoor()
Reg no
Switchonengine()
