Erzeugt ein std::regex_iterator Objekt i wie von std::regex_iterator<BidirIt, CharT, traits> i(first, last, e, flags), und nutzt sie, um durch jedes Spiel des e innerhalb der Sequenz [first,last) fort. Für jeden solchen Spiel m, kopiert den nicht angepassten Teilfolge (m.prefix()) in out wie er ist und ersetzt dann den übereinstimmenden Teilfolge mit der formatierten Ersetzungsstring, als ob durch den Aufruf m.format(out, fmt, flags). Wenn keine weiteren Übereinstimmungen gefunden werden, kopiert die verbleibenden nicht-passenden Zeichen out .

Original:

Constructs a std::regex_iterator object i as if by std::regex_iterator<BidirIt, CharT, traits> i(first, last, e, flags), and uses it to step through every match of e within the sequence [first,last). For each such match m, copies the non-matched subsequence (m.prefix()) into out as-is and then replaces the matched subsequence with the formatted replacement string as if by calling m.format(out, fmt, flags). When no more matches are found, copies the remaining non-matched characters to out.

Gleiche wie 1), aber der formatierten Ersatz wird wie durch Aufrufen m.format(out, fmt, fmt + char_traits<charT>::length(fmt), flags) durchgeführt

Original:

same as 1), but the formatted replacement is performed as if by calling m.format(out, fmt, fmt + char_traits<charT>::length(fmt), flags)
