<regex>

Defines a template class to parse 정규식(C++), and several template classes and functions to search text for matches to a regular expression object.

#include <regex>

설명

To create a regular expression object, use the template class basic_regex 클래스 or one of its specializations, regex Typedef and wregex Typedef, together with the syntax flags of type regex_constants::syntax_option_type.

To search text for matches to a regular expression object, use the template functions regex_match 함수 and regex_search 함수, together with the match flags of type regex_constants::match_flag_type. These functions return results by using the template class match_results 클래스 and its specializations, cmatch Typedef, wcmatch Typedef, smatch Typedef, and wsmatch Typedef, together with the template class sub_match 클래스 and its specializations, csub_match Typedef, wcsub_match Typedef, ssub_match Typedef, and wssub_match Typedef.

To replace text that matches a regular expression object, use the template function regex_replace 함수, together with the match flags of type regex_constants::match_flag_type.

To modify the details of the grammar of regular expressions, write a class that implements the regular expression traits.
