Basic namespace doubt

[Subhransu]

Hi All,

Just wanted to know if there is any difference between,

using namespace MyNamespace;

and

using namespace ::MyNameSpace;

Regards,

Yes. The "::" is the global namespace. The first directive might refer to some
nested MyNamespace.


Cheers & hth.,

Hi
If MyNamespace is a global level namespace, I believe there is
no difference between those two statements. Consider the namespace
std:
using namespace std;
using namespace ::std;
I think the second one is rather verbose, or more elaboration.
