Java-like annotations in C ++

Question

Is there something like Java annotations in C ++?

For example, the @Override annotation marks a function that overrides another function, and if it weren’t, it would give an error at compile time.

I am looking for something similar in C ++.

Answer 1

C ++ 0x will have this function, where you can explicitly indicate whether a member function is intended to override a base class function, use the default implementation generated by the compiler, and much more.
