Is using nested namespaces bad?

[Joseph118]

I was wondering is using nested namespaces to organize the classes in my library is good programming practice?

I was wanted to organize the classes like packages in Java.

Thanks in advance!

Yes, namespaces are designed for this. Additionally you can use the same namespace in different [header] files.

Thanks! You just made my code so much cleaner!

Actually I should have mention that the same namespace may appear more than once regardless in what file.

The C++ Standard Library has multiple files that contain stuff within namespace std.

It also has std::chrono:
http://www.cplusplus.com/reference/chrono/
That is a nested namespace, isn't it?
That is a library.
Does the C++ Standard Library follow good "programming practices"?

I rest my case.
