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?

Answer 1

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
