Manipolatori sono funzioni di supporto che permettono di controllare flussi input / output utilizzando operator<< o operator>>.

Original:

Manipulators are helper functions that make it possible to control input/output streams using operator<< or operator>>.

I manipolatori che vengono richiamati senza argomenti (ad esempio std::cout << std::boolalpha; o std::cin >> std::hex;) sono implementate come funzioni che richiedono un riferimento a un flusso come il loro unico argomento. Gli overload speciali di basic_ostream::operator<< e basic_istream::operator>> accettare puntatori a queste funzioni.

Original:

The manipulators that are invoked without arguments (e.g. std::cout << std::boolalpha; or std::cin >> std::hex;) are implemented as functions that take a reference to a stream as their only argument. The special overloads of basic_ostream::operator<< and basic_istream::operator>> accept pointers to these functions.

I manipolatori che vengono richiamati con argomenti (ad esempio std::cout << std::setw(10);) sono implementate come funzioni che restituiscono oggetti di tipo non specificato. Questi manipolatori definire la loro operator<< oppure operator>> che svolgono la manipolazione richiesto.

Original:

The manipulators that are invoked with arguments (e.g. std::cout << std::setw(10);) are implemented as functions returning objects of unspecified type. These manipulators define their own operator<< or operator>> which perform the requested manipulation.
