1)

Serializza lo stato interno della pseudo-casuale e motore numero come una sequenza di numeri decimali separati da uno o più spazi, e lo inserisce nel flusso ost. Il carattere di riempimento e le bandiere di formattazione del flusso vengono ignorati e non colpiti.

Original:

Serializes the internal state of the pseudo-random number engine e as a sequence of decimal numbers separated by one or more spaces, and inserts it to the stream ost. The fill character and the formatting flags of the stream are ignored and unaffected.

2)

Ripristina lo stato interno del pseudo-casuale e motore numero dalla rappresentazione serializzata, che è stato creato da una precedente chiamata a operator<< utilizzando un flusso con le stesse impostazioni internazionali impregnato e il CharT stesso Traits. Se l'input non può essere deserializzato, e rimane invariata e failbit è sollevata su ist

Original:

Restores the internal state of the pseudo-random number engine e from the serialized representation, which was created by an earlier call to operator<< using a stream with the same imbued locale and the same CharT and Traits. If the input cannot be deserialized, e is left unchanged and failbit is raised on ist

Se una rappresentazione testuale è stato scritto utilizzando os << x e che la rappresentazione viene ripristinato nello stesso o in un y oggetto diverso dello stesso tipo utilizzando is >> y, poi x==y.

Original:

If a textual representation is written using os << x and that representation is restored into the same or a different object y of the same type using is >> y, then x==y.
