C Plus Plus Library Regular Expressions

Key Features

◾Target sequence (subject): The sequence of characters searched for the pattern. Generally, this is a range specified by two iterators, but some functions also accept a c-string or a string object instead. ◾Regular expression (pattern): The pattern which is searched for in the target sequence. This must be an object of a basic_regex type (such as regex), generally constructed from a string with a special syntax that describes what constitutes a match (see ECMAScript syntax). ◾Matches array: Some operations allow to retrieve information about matches. This information is stored in one of the special match_results array types (such as cmatch or smatch). ◾Replacement string: Some operations can replace matches. These replacements are specified in strings that allow for a special format (see ECMAScript syntax).
