What is an Array?

An array is a group of data items given the same name for processing. Students’ scores in some subjects, when listed or arranged under a name, constitute an array.  OR

An array is a series of elements of the same type placed in contiguous memory locations that can be individually referenced by adding an index to a unique identifier. Also arrangement of items of computerized data in tabular form for easy reference and identification is regarded as an array.

Defining One-dimensional Array

An array whose values or items are arranged in only one direction is referred to as one-dimensional array. It is also called a linear list. E.g.  [2, 4, 3, 6, 7, 10, 12], [Ade, Ngozi, Zainab, Bello]

Numeric array:

It contain a set of numbers. The set is given a single name and each number in the array is called an element of the array.
