Versions 5 and 6 take an output iterator as first argument, which is used to store the resulting sequence.Īn optional parameter, flags, allows to specify options on how to match and format the expression. The resulting sequence is returned as a string object on versions 1, 2, 3 and 4. The target sequence is either s or the character sequence between first and last, depending on the version used. Makes a copy of the target sequence (the subject) with all matches of the regular expression rgx (the pattern) replaced by fmt (the replacement).
