Comparison Of Programming Languages (strings)
This comparison of programming languages (strings) compares the features of string (computer science), string data structures or text string, text-string processing for over 52 various computer programming languages. Concatenation Different languages use different symbols for the concatenation operator. Many languages use the "+" symbol, though several deviate from this. Common variants Unique variants * Awk uses the empty string: two expressions adjacent to each other are concatenated. This is called Juxtaposition (literary), juxtaposition. Unix shells have a similar syntax. Rexx uses this syntax for concatenation including an intervening space. * C (programming language), C (along with Python) allows juxtaposition for string literals, however, for strings stored as Character (computing), character Array data structure, arrays, the strcat function must be used. * COBOL uses the STRING statement to concatenate string variables. * MATLAB and Octave programming language, Octa ...

String (computer Science)
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). A string is generally considered as 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. ''String'' may also denote more general arrays or other sequence (or list) data types and structures. Depending on the 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. When a string appears literally in source code, it is known as a string literal or an anonymous string. In formal languages, which are used in mathematical ...
