Look up

Encapsulation
Inheritance
Polymorphism

Those are the 3 major paradigms that are implemented through classes. Wikipedia has passable explanations of all three.

Do you already know other computer languages [which ones?] and seek to add C++; or are you in the process of learning your first computer language?

[varunreddy]

i know c language,but c++ is bit confusing

[donbock]

I don't use C++, but as I understand it there are three ways to use C++ ...

• ... as a better C. You take advantage of some C++ features, but still write procedural code.
• ... as an object-oriented (OO) convert. You need a completely new way of thinking that involves classes, inheritance, polymorphism, templates, and all that jazz.
• ... hybrid. Dip your toe into OO stuff but still write mostly procedural code.

Which path do you have in mind?

[varunreddy]

object-oriented covert path
