Definition: array
An ordered arrangement of data items. A vector is a one dimensional array; a matrix is a two-dimensional array. Arrays are used in myriad applications from basic database processing to scientific simulation. Most programming languages support arrays by providing indexes into the data. For example, with indexes starting at zero, the hypothetical programming statement Employee[4][9] points to the fifth record (row) and tenth data item (column) of an employee array. See subscript, index and data item.
Array Programming
With array indexes starting at 0, in the top array, City would be programmatically identified as Customer[3] (fourth data item). Sales[1][2] would refer to the March figures for Widgets in the bottom array.
