//fuctions here...
}
}

Yes. You can nest classes within classes and functions and you can nest
namespaces within namespaces.

i.e.

namespace X {
namespace Y {
struct A {
struct B {
void F() {
class C {};
}
};
};
};
};

Yes. You can nest classes within classes and functions and you can nest
namespaces within namespaces.

i.e.

namespace X {
namespace Y {
struct A {
struct B {
void F() {
class C {};
}
};
};
};
};

but don't put semicolons after namespaces because it isn't standard
conforming.

namespace X {
namespace Y {
struct A {
struct B {
void F() {
class C {};
}
};
};
}
}
