Array Basic Input and Output in Ruby

In this article, I would like to share with you a simple program that I wrote using Ruby programming language that will ask the user a series of an integer number and display the given integer number by the user in the screen using one-dimensional arrays. I am using Eclipse PHP IDE as my editor in writing this Ruby script.
