Member function with static linkage

Question

I\'m trying to understand why the following is an error:

class Foobar {
 public:
  static void do_something();
};

static void Foobar::do_something() {} // E

This question is already well answered. Details for static can be read here

Golden Rule: The static keyword is only used with the declaration of a static member, inside the class definition, but not with the definition of that static member.
