Regular expression is not C++ specific.

A regular expression is simply a pattern for text, e.g., you might have two
letters, followed by a dash, followed by four digits.

Regular expressions are used for various types of text processing, e.g.,
search and replace or the validation of input (to make sure it is in the
correct format).

A library for processing regular expressions is here:
