Answer 2

Accessing static functions perhaps, everything else is a member access operator (dot/arrow).

Answer 3

Or to resolve the scope (namespace/class) the function is in.
Like std::* things.

Answer 4

More like; used to access member functions of a class. That's why it doesn't need to be used in friend functions (because, friend functions aren't inside the class). Besides, the only time you wouldn't need it for a friend function is if the friend function is within the reach (or scope) of your current call.
