Namespace scope

[dleanjeanz]

If I have a header and a few class like this:

namespace ns {
     class Human;
     class Animal;
}

class Human {

};

class Animal {

};

Can I just put these classes in namespace ns and write them outside of its scope without making them global? And if I can't, is there any way I can make it possible?

You mean something like this?

namespace x
{
  class y;
}

class x::y
{};

int main(){}

I think so. Thanks
