      std::back_insert_iterator est un OutputIterator qui ajoute à un conteneur pour lequel il a été construit, en utilisant la fonction du conteneur push_back() membre lorsque l'itérateur (que ce soit déréférencé ou non) est assigné. L'incrémentation du std::back_insert_iterator est un no-op .
      Original:
