Regular expressions library (since C++11) - cppreference.com
The regular expressions library provides a class that represents regular expressions, which are a kind of mini-language used to perform pattern matching within strings. Almost all operations with regexes can be characterized by operating on several of the following objects: These classes encapsulate a regular expression and the results of matching a regular expression within a target sequence of characters. These functions are used to apply the regular expression encapsulated in a regex to a target sequence of characters. The regex iterators are used to traverse the entire set of regular expression matches found within a sequence. This class defines the type of objects thrown as exceptions to report errors from the regular expressions library. The regex traits class is used to encapsulate the localizable aspects of a regex. Output:
From cppreference.com The regular expressions library provides a class that represents regular expressions, which are a kind of mini-language used to perform pattern matching within strings. Almost all operations with regexes can be characterized by operating on several of the following objects: Target sequence. The character sequence that is searched for a pattern. This may be a range specified by two iterators, a null-terminated character string or a std::string. Pattern. This is the regular expression itself. It determines what constitutes a match. It is an object of type…
