This looks like homework and you don't show any actual code that you have tried.

I think this page will tell you how to do what you want.

Please do not reopen old questions and post just a link: it looks like abusive behavior we call "rep point farming" and can get you kicked off the site.

In this case, the original question was homework, and after a year it is unlikely to be accepted if the OP hands it in!
In addition, when the solution you propose is just a link it will get you sent to moderation as a probable spammer.

I'm pretty sure that you are neither of these things, but do try to stick to "modern" questions to avoid suspicion in future.
