Quizplus · Accepted Answer

The correct choice is regex_token_iterator because this iterator allows us to iterate through the parts of a string that match a regular expression and also allows us to define which parts of the string we want to extract based on the regular expression. The other choices, regex_iterator and string_iterator, do not provide this functionality. string_match_iterator is not a valid option as it is not a standard iterator in C++.
