std::insert_iterator is an output iterator that inserts elements into a container for which it was constructed, at the position pointed to by the supplied iterator, using the container's insert() member function whenever the iterator (whether dereferenced or not) is assigned to. Incrementing the std::insert_iterator is a no-op.
