So you are saying that you want some code that someone has done before that you can copy. Well you are free to look for it, but don’t expect me to look for it for you when it is something so simple. I am willing to spend time teaching you how to write this because I want you to learn and not have to look for examples of every simple thing. So it is up to you, engage in the learning process we me and other here, or go and search for something that you would probably not recognise if you saw it.
