[ fromfile: namespaces.xml id: anonymousnamespace ]

A namespace without a name is an anonymous namespace. This is similar to a static global, or file scope identifier. It is accessible from that point, down to the end of the file.^[118]

Example 20.16 shows how anonymous namespaces can eliminate the need for static globals.

namespace {
    const int MAXSIZE = 256;
}

void f1() {
    int s[MAXSIZE];
}
