formatiert sind Output-Funktionen: Sie beginnen die Ausführung durch den Bau ein Objekt vom Typ sentry, die spült die tie()'d Ausgabepuffer wenn nötig und die Stream-Fehler überprüft. Nach dem Bau, wenn die Wache Objekt kehrt false, geben diese Funktionen, ohne den Versuch keine Ausgabe. Wenn ein Fehler auftritt während der Ausgabe, rufen Sie diese Funktionen setstate(ios_base::failbit). Wenn eine Ausnahme während der Ausgabe ausgelöst wird, dann ios :: badbit gesetzt ist (die Ausnahme unterdrückt sofern exceptions()&badbit) != 0, in welchem ​​Fall es wird erneut ausgelöst)
Original:
are formatted output functions: they begin execution by constructing an object of type sentry, which flushes the tie()'d output buffers if necessary and checks the stream errors. After construction, if the sentry object returns false, these functions return without attempting any output. If an error occurs during output, these functions call setstate(ios_base::failbit). If an exception is thrown during output, then ios::badbit is set (the exception is suppressed unless exceptions()&badbit) != 0, in which case it is rethrown)

Original:
Inserts a character ch. If the type of the character is not CharT, it is first converted with os.widen(ch). Padding is determined as if by Stage 3 of num_put::put(). After insertion, width(0) is called.
