where is standard namespace?

[Mark S.]

Hi,

In the context of

using namespace std;

where is the location of the standard namespace.

I know that when you use #include<iostream>
the iostream is stored inside the VC98\Include folder.

Can the standard namespace be located in those kind of terms.

Any related information appreciated
Thanks

Mark S.

Do you know what a namespace is? A namespace is a scope wrapper that you can put around your code to distinguish it from other variables with the same identifier. It looks like:

namespace foo {
// My foo code
}

All standard library classes and functions are placed inside of the standard namespace. Thus you can either qualify all instances of identifiers from the libraries with std:: or you could do as you showed and use the using directive.

The standard namespace (or std) wraps the whole of the standard library facilities. It is thus spread through several libraries (consequently files).
