The text processing library includes components for dealing with text.

[edit]Localization library

The headers<locale> and<clocale> provide internationalization support for character classification and string collation, numeric, monetary, and date/time formatting and parsing, and message retrieval.

[edit]Regular expressions library(since C++11)

The header<regex> provides a class that representsregular expressions, which are a kind of mini-language used to perform pattern matching within strings.

[edit]Formatting library(since C++20)

The header<format> provides facilities for type-safe and extensible string formatting that is an alternative to theprintf family of functions, and intended to complement the existing C++ I/O streams library.

[edit]Null-terminated sequence utilities

Null-terminated character sequences (NTCTS) are sequences of characters that are terminated by a null character (the value aftervalue-initialization).

The strings library provides functions to create, inspect, and modify such sequences:

• null-terminated byte strings (NTBS) helper functions (including support ofwide character types),
• null-terminated multibyte strings (NTMBS) helper functions.

[edit]Primitive numeric conversions(since C++17)

In addition to sophisticated locale-dependent parsers and formatters provided by theC++ I/O library, theC I/O library,C++ string converters, andC string converters, the header<charconv> provides light-weight, locale-independent, non-allocating, non-throwing parsers and formatters for arithmetic types.
