OBJECT ORIENTED PROGRAMMING

oops  : object oriented programming style

* includes class

ex

making templet animal

class : animal : type of animal

                         name 

                         sound 

by using that template let we make a animal dog having specification under that template

so some data/ variable comes out 

animal.typeofanimal = dog

animal.name = tommy

animal.sound = bark

Object orientation

make class : inside class  make object

will treat data as a critical elements

decomposes the problem onto objects

like animal is class and dog , cat are objects

Terminology

Class : basic templet

Object : basic run time entities under some class

Data Abstraction and Encapsulation : wrapping data and function into single units

inheritance : Properties of one class can be inherited into others

Polymorphism : ability to take more than one  form (ex : func. overload)

Dynamic Binding: Code which will execute is not known until the program runs

Message passing: passing info between objects call format object.message(information)

Benefits

*Better code reussability using object anfd inheritance

* Data hiding is amazing

* multiple object can exists

*software complexity can easily be maintaned
