    Ein ForwardIterator ist ein Iterator, der Daten aus dem Element lesen kann, auf das er zeigt.

    Im Gegensatz zu einem InputIterator bleibt er auch in Multipass-Algorithmen gültig.

    Anforderungen

    Zusätzlich zu den oben genannten Anforderungen für einen Typ It ein Forwardterator sein, muss eine Instanz des i It:

    Expression Return Equivalent expression Notes
    ++i const It& After this, copies of i are still valid
    i++ value_type temp = *i; ++i; return temp;
    *i++ reference

    A mutable ForwardIterator ist ein ForwardIterator, die zusätzlich erfüllt die OutputIterator Anforderungen .
