Hello everyone,

I have a situation. I've been looking through Programming Forums for an answer to my question, an i havent found it yet. So i've dicided to ask for the answer here in the C forum.

I want to know the EXACT meaning of Object Oriented Programming, because this has peeked my curiousity for a long time now. I've looked through, google, yahoo, altavista, ect, and what i get is a definition that is not understandable at all to me!

So in other words, can anyone explain what Object Oriented Programming is in simple ENGLISH? or at least try to. I know a some C programming, so i think i might be able to understand some of the terminology. Any help would be greatly appreciated. Thank you.

Haven't read it myself, but a quick Google search turned that up.

C is not an Object Oriented (OO for short) programming language. It is a functional language. What this means is that you write the programs as set of functions.

In OO, you write a program as a collection of communicating objects. OK then what is an object? Object is a thing with its own data and fucntionality to process the data.

The differenace is that in fuctional programming, data belongs to all functions and data flows through fuctions. But in OO, data will blong to where they belong, that is objects, and the object classes will know what to do with data.

It is kind of tough to explain this without diagrams, but I hope I tried.

I know C is not an OO language, but it's perfectly possible to do OO programming in C. It's just a bit more difficult.

By the way C is not a functional language, I have no idea where you got that idea.

Object oriented design is the kind of design most easily accomodated by the human brain. It is converted to a more procedural approach for today's common processors because they are incapable of dealing directly with the process. OOD is not an invention of software gurus. It has been around for ages. Look at the design of physical objects all around you. Think of your software designs in the same terms. You will need layers of abstraction between your design and the machine implementation. One can afford it, these days.

Object Orientation provides a level of abstraction for the programmer. Kind of like, you only care if the car cranks, not what is under the hood.
