String (computing)¶
In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable.
Core Idea¶
String (computing) is treated here as the recurring computerscienceandinformation identity summarized by this source-grounded definition: In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable. In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable. The latter may allow its elements to be mutated and the length changed, or it may be fixed (after creation).
Scope of Application¶
-
Non-text strings. This data may or may not be represented by a string-specific datatype, depending on the needs of the application, the desire of the programmer, and the capabilities of the programming language.
-
Character string functions. String functions are used to create strings or change the contents of a mutable string.
-
Purpose. A primary purpose of strings is to store human-readable text, like words and sentences.
-
Purpose. Strings are used to communicate information from a computer program to the user of the program.
-
Purpose. Often these are intended to be somewhat human-readable, though their primary purpose is to communicate to computers.
Clarity¶
A clear use of String (computing) names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable.
Manages Complexity¶
String (computing) compresses multiple computerscienceandinformation details into a stable diagnostic relation. The source shows both the central mechanism—the name stringology was coined in 1984 by computer scientist Zvi Galil for the theory of algorithms and data structures used for string processing.—and the practical consequence—the string length can be stored as a separate integer (which may put another artificial limit on the length) or implicitly through a termination.
Abstract Reasoning¶
- Type the carrier. Identify the computerscienceandinformation entities to which the claim applies.
- State the relation. Use the source-grounded identity: In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable.
- Check operation and conditions. Sammet, "the first realistic string handling and pattern matching language" for computers was COMIT in the 1950s, followed by the SNOBOL language of the early 1960s.
- Demand recognition evidence.
Knowledge Transfer¶
Within the home domain. Knowledge about String (computing) transfers literally when a new case preserves the same carrier type, relation, and recognition test. This data may or may not be represented by a string-specific datatype, depending on the needs of the application, the desire of the programmer, and the capabilities of the programming language being used. String functions are used to create strings or change the contents of a mutable string. Beyond the home domain. No canonical parent is asserted for String (computing).

-
String (computing) is a kind of Data Type Domain-specific
String (computing) satisfies the defining boundary of Data Type: A data type is a specification of a class of values together with their representation or abstract behavior, admissible operations, invariants, equality and error conventions, and static or dynamic rules governing storage, construction, use, and composition in a computational system.

Neighborhood in Abstraction Space¶
String (computing) sits in a sparse region of the domain-specific corpus (65th percentile for distinctiveness): few abstractions share its structure, so a faithful description tends to retrieve it precisely.
