Define the term - Array

A fixed length, ordered collection of values of same type stored in contiguous memory locations; collection may be ordered in several dimensions.

Values stored in an array are known as elements. Elements are accessed by indexing into array: an integer value is used to indicate ordinal value of the element. For instance, if a is an array with 20 elements, then a [6] is the element of a with ordinal value 6. Indexing may start at any number, but normally it starts at 0. In the instance above a[6] is the seventh value in a when indexing start at 0.
