      std::regex_iteratorまるでiによってstd::regex_iterator<BidirIt, CharT, traits> i(first, last, e, flags)オブジェクトを構築し、シーケンス内e[first,last)のすべての試合をステップ実行するためにそれを使用しています。このような各マッチmため、as-isのm.prefix()に非整合subsequenceを（out）コピーしてm.format(out, fmt, flags)を呼び出したかのようにフォーマットされた置換文字列と一致する部分列を置き換えます。これ以上マッチが発見された場合は、outに残りの非マッチした文字をコピーします.
      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.
