The class template std::match_results holds a collection of character sequences that represent the result of a regular expression match.
This is a specialized allocator-aware container. It can only be default created or modified by passing to the std::regex_search() or std::regex_match() algorithms.
The first sub_match (index 0) contained in a match_result always represents the full match within a target sequence made by a regex, and subsequent sub_matches represent sub-expression matches corresponding in sequence to the left parenthesis delimiting the sub-expression in the regex.
