however i got problem to do the looping as my lecturer want me to...can anyone teach me how to do it?
Please detail your problem: what exactly do you need to accomplish and what is your trouble about?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.
This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong. -- Iain Clarke -

First of all, please, use
<pre>tags around code snippets. Why don't you wrap that code inside a function and then iteratively call it?If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.
