    Construit un objet std::regex_iterator i comme par std::regex_iterator<BidirIt, CharT, traits> i(first, last, e, flags), et l'utilise pour faire dfiler tous les matches de e dans le [first,last) squence. Pour chaque match de tels m, copie la sous-squence non apparie (m.prefix()) dans out comme a, et puis remplace la sous-squence correspond la chane de remplacement format comme si en appelant m.format(out, fmt, flags). En l'absence de plus de correspondances sont trouves, copie les autres non apparis caractres 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.
