Costruisce un oggetto std::regex_iterator i come per std::regex_iterator<BidirIt, CharT, traits> i(first, last, e, flags), e lo usa per scorrere tutte le partite del e all'interno del [first,last) sequenza. Per ogni partita m tale, copia il non appaiato sottosequenza (m.prefix()) in out così come sono e quindi sostituisce il sottosequenza abbinato con la stringa di sostituzione formattata come se chiamando m.format(out, fmt, flags). Quando non vengono reperite altre corrispondenze, copia i restanti non corrispondenza caratteri 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.

Se non ci sono partite, copia l'intera sequenza in out così come sono.
Original:
If there are no matches, copies the entire sequence into out as-is.

Se flags contiene std::regex_constants::format_no_copy, i non-corrispondenza sottosequenze non vengono copiate nel out.
Original:
If flags contains std::regex_constants::format_no_copy, the non-matched subsequences are not copied into out.

Se flags contiene std::regex_constants::format_first_only, solo la prima corrispondenza è sostituito.
Original:
If flags contains std::regex_constants::format_first_only, only the first match is replaced.

come 1), ma la sostituzione formattato viene eseguita come se chiamando m.format(out, fmt, fmt + char_traits<charT>::length(fmt), flags)

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

Costruisce un result stringa vuota di std::basic_string<CharT, ST, SA> tipo e chiama std::regex_replace(std::back_inserter(result), s.begin(), s.end(), e, fmt, flags).
Original:
Constructs an empty string result of type std::basic_string<CharT, ST, SA> and calls std::regex_replace(std::back_inserter(result), s.begin(), s.end(), e, fmt, flags).
