in c++ do structures support the object oriented principles?? – Prashant Feb 07 '11 at 09:58

If you're talking about C++ then mention this in the question and add a `C++` tag. – Paul R Feb 07 '11 at 09:59

5do you own any C++ books? if yes then why dont you try searching this in that ? – Harry Joy Feb 07 '11 at 09:59

There are no structures in C++. The `struct` keyword can be used to declare or define classes, just like the `class` and `union` keywords. – Philipp Feb 07 '11 at 10:11

in C++, there is almost no difference between struct and class. yes OOP is available with the keyword struct.
you can consider both class and struct the same except that:
- by default visibility in struct is public, while it's private for class
- by default inheritance in struct is public: while it's private for class.

There is no difference between struct and class in C++ except that struct members are public by default and class members are private by default. What ever else holds for class holds for struct as well in C++.

@Ashot : Yes, but Stephane has mentioned it. I believe OP should understand anything by default is public in struct and private in class. That is what I meant. Thanks. – Mahesh Feb 07 '11 at 10:12

1The same as the others said. I was too late, and since it's already been said a thousand times, I'll delete my comment. But mentioning the difference with respect to inheritance visibility is extremely important and often forgotten. – Philipp Feb 07 '11 at 10:23

in C++ and .NET you can have methods defined for a struct as well, in C++ a struct has all members public by default while a class has members private by default. A struct can implement an interface but cannot derive a base class.
structs are value types while classes are reference types.
In my opinion and point of view since a struct cannot derive another class, it does not fully support OOP, that's why we have classes. :)

Not a .NET question (admittedly, was only revealed later on, therfore no downvote). Extra credit for not preaching the irrelevant and wrong "structs go to stack" though. – Feb 07 '11 at 10:01
