Example of array of 10 int types:

int[] numbers = new int[10];

Example of array of 3 string types:

string[] words = { "these", "are", "arrays" };

You can also declare the size of the array and initialize the values at the same time:

int[] more_numbers = new int[3]{ 21, 14 ,63 };


For Multi-Deminsional arrays you declare them the same except for a comma in the type declaration.

The following creates a 3x2 int matrix
int[,] number_matrix = new int[3,2];

As with the previous examples you can also initialize the values of the array, the only difference being each row in the matrix must be enclosed in its own braces.

string[,] string_matrix = { {"I","swam"}, {"in","the"}, {"freezing","water"} };

or

string[,] funny_matrix = new string[2,2]{ {"clowns", "are"} , {"not", "funny"} };

==[[Clean]]==
[[Category:Clean]]
Array denotations are overloaded in Clean, therefore we explicitly specify the types. There are lazy, strict, and unboxed array.
===Lazy array===
Create a lazy array of strings using an array denotation.
array :: {String}
array = {"Hello", "World"}
Create a lazy array of floating point values by sharing a single element.
array :: {Real}
array = createArray 10 3.1415
Create a lazy array of integers using an array (and also a list) comprehension.
array :: {Int}
array = {x \\ x <- [1 .. 10]}
===Strict array===
Create a strict array of integers.
array :: {!Int}
array = {x \\ x <- [1 .. 10]}
===Unboxed array===
Create an unboxed array of characters, also known as <tt>String</tt>.
array :: {#Char}
array = {x \\ x <- ['a' .. 'z']}

==[[Common Lisp]]==
[[Category:Common Lisp]]
Creates a one-dimensional array of length 10. The initial contents are undefined.
(make-array 10)
Creates a two-dimensional array with dimensions 10x20.
(make-array '(10 20))

==[[Forth]]==
[[Category:Forth]]

Forth has a variety of ways to allocate arrays of data, though it has no built-in array handling words, favoring pointer manipulation.

Static array of 200 cells, uninitialized:

create MyArray 200 cells allot
here MyArray - cell / constant MyArraySize

Static array containing the numbers 1 to 5

create MyArray 1 , 2 , 3 , 4 , 5 ,
here MyArray - cell / constant MyArraySize

Dynamic array allocation:
0 value MyArray
200 cells allocate throw to MyArray

Dynamic array free:
MyArray free throw
0 to MyArray

==[[Fortran]]==
[[Category:Fortran]]

Default case:

integer a(10)

this will have ten elements. Counting starts at 1. If a zero-based array is needed, declare like this:

integer a(0:9)

this mechanism can be extended to any numerical indices, and allowed number of dimensions (and of course to other data types than integers). For example

real*8 (25:29,12)

will be an two-dimensional, 5x12-array of 8-byte floats, where the first dimension can be addressed numerically as 25, 26, 27, 28 or 29 (and the second dimension as 1 .. 12).


==[[IDL]]==
[[Category:IDL]]

IDL doesn't really distinguish between scalars and arrays - the same operations that can create the one can <i>usually</i> create the other as well.

a = 3
help,a
A INT = 3

a = [3,5,8,7]
help,a
A INT = Array[4]

==[[OCaml]]==
[[Category:OCaml]]
Using an array literal:

let array = [| 1; 2; 3; 4; 5 |];;

To create an array of five elements with the value 0:

let num_items = 5 and initial_value = 0;;
let array = Array.make num_items initial_value

To create an array with contents defined by passing each index to a callback (in this example, the array is set to the squares of the numbers 0 through 4):

let callback index = index * index;;
let array = Array.init 5 callback

Toka allows creation of an array using is-array. Access to the elements is done using
get-element, put-element, get-char-element, and put-char-element functions. You can
not initialize the values automatically using the core array functions.

100 cells is-array foo
100 chars is-array bar

Creating an Array was a programming task. It has been deprecated for reasons that are discussed in its talk page.

Please do not add new code, and merge existing code to the Arrays task.

This task is about numerically-indexed arrays. For hashes or associative arrays, please see Creating an Associative Array.

In this task, the goal is to create an array. Mention if the array base begins at a number other than zero. In addition, demonstrate how to initialize an array variable with data.
