String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.

The user can search for elements in an associative array, and delete elements from the array. The following shows how multi-dimensional associative arrays can be simulated in standard AWK using concatenation and the built-in string-separator variable SUBSEP:
print_int x or print_endline str or Printf.printf format x ... prerr_int x or prerr_endline str or Printf.eprintf format x ... F#: let x = System.Console.ReadLine() printf format x ... or printfn format x ... eprintf format x ... or eprintfn format x ... Standard ML: val str = TextIO.inputLIne TextIO.stdIn: print str: TextIO. output (TextIO ...
For example, in the Pascal programming language, the declaration type MyTable = array [1.. 4, 1.. 2] of integer, defines a new array data type called MyTable. The declaration var A: MyTable then defines a variable A of that type, which is an aggregate of eight elements, each being an integer variable identified by two indices.
Array indices can also be arrays of integers. For example, suppose that I = [0:9] is an array of 10 integers. Then A[I] is equivalent to an array of the first 10 elements of A. A practical example of this is a sorting operation such as:
As an example consider the C declaration int anArrayName[10]; which declares a one-dimensional array of ten integers. Here, the array can store ten elements of type int. This array has indices starting from zero through nine. For example, the expressions anArrayName[0] and anArrayName[9] are the first and last elements respectively.
Some implementations provide options for determining what is recognized as a printable character, which is useful for finding non-ASCII and wide character text. By default, it only prints the strings from the initialized and loaded sections of object files; for other types of files, it prints the strings from the whole file.
