An array is a grouping of two or more variables of the same type. Values are stored at the indexed locations in the list.
A list of movies you'd like to see is an example of a one dimensional array
Index Value 1. Moulin Rouge! 2. Romeo + Juliet 3. Strictly Ballroom For a one dimensional array, you only need one index value for each unique location. The value stored at location 3 is "Strictly Ballroom".
The multiplication table is an example of a two dimensional array.
1 2 3 1 1 2 3 2 2 4 6 3 6 8 9 For a two dimensional array, you need two index values for each unique location. The value stored at location row 2 column 3 is 6.
Declaring an array depends on the programming language:
Visual Basic Family Dim SongList(5) As String Creates an array with 6 elements indexed from 0 to 5. Java String songList[] = new String[5];
String songList[] = {comma-separated list of elements};Creates an array of 5 elements indexed from 0 to 4. JavaScript var songList = new Array(5);
var songList = new Array(comma-separated list of elements);Creates an array of 5 elements indexed from 0 to 4.
Resizing an array depends on the programming language:
Visual Basic Family Dim SongList() As String Redim SongList(5)
Redim Preserve SongList(5)Java Can't be done. JavaScript var songList = new Array(5); songList[10] = "Your Song";
