String manipulation (or string handling) is the process of changing, parsing, splicing, pasting, or analyzing strings. String manipulation typically comes as a mechanism or a library feature of in most programming languages.
Typically, most programming languages provide a string data type that holds a sequence of characters. Such types often expose a set of functions and various other low-level functionality for manipulating the contained characters.
Common operations
- Concatenation is the process of joining two strings together into a single string. For example "
race" concatenated with "car" results in "racecar". - Splitting is the process of breaking down a string into multiple strings according to a certain delimiter or rule (e.g. regex pattern). For example "
A B C" could be split into three separate strings, ("A", "B", "C"), using the space character as a delimiter. - Substrings is the process of extracting a portion of the string from a bigger string. Such operations typically involve a starting offset and a length. For example, one possible substring of "
apples" is "pp". - Case conversion is the process of converting a string into a specific case for example into all lowercase or titlecase.
- Searching is the process of searching for a specific pattern in a string.
In various languages
Most programming languages provide a built-in mechanism or library functions for manipulating strings.
