Arrays

An array is a special variable that can hold more than one value at a time. It is essentially a list of items.

Indexing

Items in an array are accessed using their index number. In almost all programming languages, arrays are zero-indexed, meaning the first item is at index 0, the second is at index 1, and so on.
