Can a class share a namespace's name?


Keywords:c++ 


Question: 

Is the following C++ code valid?

namespace Foo
{
    class Bar
    {
        // Class code here.
    };
}

namespace Foo
{
    namespace Bar
    {
        void SomeFunction();
        {
            // Function code here.
        }
    }
 }

In other words, can there be a namespace with the same name as a class?


2 Answers: 

You cannot have the arrangement you have in your question because there is no way to disambiguate Bar.

My compiler says:

error C2757: 'Bar' : a symbol with this name already exists and therefore this name cannot be used as a namespace name


"can there be a namespace with the same name as a class?"

No, If they are in the same namespace, as in your case.

Otherwise, yes. Anything can have the same name as anything else if they are in different namespaces. See this stackoverflow thread as reference.
