Thank you sir,
Can you tell me what is Object orientated actually?

 

In a nutshell

1. Objects have data.
2. Objects execute procedures.
3. Objects implement behavior.

In theory you don't have to know anything about the internals in order to use them.

Probably far more information found there than someone can possibly handle here.
