An Array is a collection of data, typically arranged in either a line, and/or a rectangular or cubic field. If you work in an office, you may have a stacked mail box for the employees in your company. This is a good real world example of an array. The typical spreadsheet table is an array. In computer programming, arrays are very common, and a great way to hold and process information. In Cinema 4D, arrays are available to artists, typically in the MoGraph Cloner, but in other operations as well. You will recognize an array when you set and X by Y (and/or Z) values for your clones.
