When a string appears literally in source code, it is known as a string literal or an anonymous string.
Discussionĭepending on programming language and precise data type used, a variable declared to be a string may either cause storage in memory to be statically allocated for a predetermined maximum length or employ dynamic allocation to allow it to hold a variable number of elements. A string is generally considered a data type and is often implemented as an array data structure of bytes (or words) that stores a sequence of elements, typically characters, using some character encoding. The latter may allow its elements to be mutated and the length changed, or it may be fixed (after creation).
Kenneth Leroy Busbee and Dave Braunschweig OverviewĪ string data type is traditionally a sequence of characters, either as a literal constant or as some kind of variable.
