The class provides some typical string operations like comparison, concatenation, find and replace, and a function for obtaining substrings An example would be the conversion of an integer value into a floating point value or its textual representation as a string, and vice versa [8] the individual units making up the string are of type char.

The c programming language has a set of functions implementing operations on strings (character strings and byte strings) in its standard library
Various operations, such as copying, concatenation, tokenization and searching are supported
A string of n characters is represented as an array of n. 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. A string homomorphism (often referred to simply as a homomorphism in formal language theory) is a string substitution such that each character is replaced by a single string.
Escape sequences in c in the c programming language, an escape sequence is specially delimited text in a character or string literal that represents one or more other characters to the compiler It allows a programmer to specify characters that are otherwise difficult or impossible to specify in a literal. A literal compiles to an array of the specified char values with a terminating null terminating character to mark the end of the string
