Localization library

From cppreference.com
< cpp
 
 
 

The locale facility includes internationalization support for character classification and string collation, numeric, monetary, and date/time formatting and parsing, and message retrieval. Locale settings control the behavior of stream I/O, regular expression library, and other components of the C++ standard library.
