String is a data type used in computer programming language and data storage. It is made up of a series of characters, numbers, symbols, and spaces, in order to store and represent text-based information. Strings can be implemented in many different programming languages, and are commonly used for text-based manipulation and storage of large amounts of data.
In computing, a string is represented as a contiguous sequence of bytes, in either a fixed or vaiable-length format, depending on the programming language. Strings can contain any combination of characters, numbers, symbols, spaces, and other characters, and can be of up to several megabytes in size. Generally, strings are thought of as an ordered sequence of characters; however, the actual nature of the string depends on the programming language used.
Most programming languages allow for string manipulation, such as searching for characters or substrings, concatenating strings, and comparing strings. Other operations such as capitalization and reversing can also be performed on strings. Many languages also support regular expression syntax, which simplifies complex string manipulation and searching.
String data types can also be used as a key-value storage mechanism; they can store key-value data as a string of individual keywords separated by a delimiter. This is commonly used to store large amounts of data in a readable and manageable format, such as JSON and XML.
Strings are an important and integral part of programming languages, and can often be the source of significant complexity. Despite this, the versatile and powerful nature of strings make them an integral part of most modern programming languages.
