std::ostream_iterator è un passaggio singolo iteratore di output che scrive gli oggetti successivi di tipo T nell'oggetto std::basic_ostream per il quale è stato costruito, utilizzando operator<<. Opzionale delimitatore di stringa viene scritto nel flusso di output dopo ogni operazione di scrittura. L'operazione di scrittura viene eseguita quando l'iteratore (se referenziato o meno) è assegnato. Incremento del std::ostream_iterator è un no-op.
Original:
std::ostream_iterator is a single-pass output iterator that writes successive objects of type T into the std::basic_ostream object for which it was constructed, using operator<<. Optional delimiter string is written to the output stream after every write operation. The write operation is performed when the iterator (whether dereferenced or not) is assigned to. Incrementing the std::ostream_iterator is a no-op.

In una tipica implementazione, i membri dei soli dati di std::ostream_iterator sono un puntatore al std::basic_ostream associato e un puntatore al primo carattere della stringa delimitatore.
Original:
In a typical implementation, the only data members of std::ostream_iterator are a pointer to the associated std::basic_ostream and a pointer to the first character in the delimiter string.

Durante la scrittura di caratteri, std::ostreambuf_iterator è più efficiente, dato che evita il sovraccarico di costruire e distruggendo l'oggetto sentinella una volta per carattere.
Original:
When writing characters, std::ostreambuf_iterator is more efficient, since it avoids the overhead of constructing and destructing the sentry object once per character.
