Question

What is the difference between Object-Oriented Programming and Procedural Programming?

What are the advantages and disadvantages of each?

Answer 1

OOP:
- Objects communicating with each other .
Procedural Programming :
- Function communictaing with each other (calling each other )

-- I think one of the most OOP Advantages is Abstraction.
ie : you are programming in general NOT to a special perpose
ex :For a class "car" :
You're not programming for the red car from the xxxx manufacturer company ...etc , You are programming for all cars .which they share in many attrinutes ...

So I think when you're programming a special thing for special perpose you could use Procedural programing but when you need generality you should use OOP

-- Other advantage of OOP is : Modularity:
The breaking up of something complex into manageable pieces
-- another one is Inheritence ...
ex : when you program the car class and the truck class .... there is some common things between them so you could make another class named :vehicle and make them exteds it .
so OOP makes it easy to maintain and modify existing code as new objects can be created with small differences to existing ones.

-An advantage of Procedural Programming : Needs less memory.
-A Disadvantage of Procedural Programming :
**** Difficult to relate with real world objects.
**** You don't concentrate on the data as much as you do on the operation between them , and in the OOP There is data and oooooonly data ....
when you know how to define the object in a right way then you're program is finished !

at the end I think you choose what to ust (PP or OOP ) depending on the programming language
for me , I'm using java at most so I have to use OOP
I don't know perl , It includes OOP but I don't know any one using OOP with it .....
anyway it's my viewpoint, maybe others would disagree with me :)
