Most of the functions that operate on c strings are declared in the string.h header (cstring in c++), while functions that operate on c wide strings are declared in the wchar.h header (cwchar in c++) For example, the string (enclosed by apostrophes) These headers also contain declarations of functions used for handling memory buffers

The name is thus something of a misnomer
Functions declared in string.h are extremely popular since, as a.
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both) In computer science, in the area of formal language theory, frequent use is made of a variety of string functions However, the notation used is different from that used for computer programming, and some commonly used functions in the theoretical realm are rarely used when programming This article defines some of these basic terms.
The c++ standard library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file i/o), support for some language features, and functions for common tasks such as finding the square root of a number The c++ standard library also incorporates most headers of the iso c standard library. Trimming (computer programming) in computer programming, trimming (trim) or stripping (strip) is a string manipulation in which leading and trailing whitespace is removed from a string
