class - C++ Multiple classes with same name

Question

Say I have two different cpp files. Both declare classes with the same name, but perhaps a totally different structure (or perhaps the same structure, different implementation). The classes do not appear in the header files. (As an example, suppose they are Node classes for different list classes.)

I've seen these classes conflict. Is this expected by the standard? What solutions are there to this problem?

UPDATE:

As suggested by answers/comments, anonymous namespaces are what I was looking for.

Answer 1

The standard way around this problem is to wrap the classes in different namespaces.
