Creating an Array was a programming task. It has been deprecated for reasons that are discussed in its talk page.
Please do not add new code, and merge existing code to the Arrays task.
This task is about numerically-indexed arrays. For hashes or associative arrays, please see Creating an Associative Array.
In this task, the goal is to create an array. Mention if the array base begins at a number other than zero. In addition, demonstrate how to initialize an array variable with data.
