Various operations, such as copying, concatenation, tokenization and searching are supported A string of n characters is represented as an array of n. In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable. 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.
String functions common to many languages are listed below, including the different names used The below list of common functions aims to help programmers find the equivalent function in a language Note, string concatenation and regular expressions are handled in separate pages Statements in guillemets (« … ») are optional. Alternative names are c string, which refers to the c programming language and asciiz[1] (although c can use encodings other than ascii. C syntax is the form that text must have in order to be c programming language code
Mismatch between the format specifiers and count and type of values results in undefined behavior and possibly program crash.
