Did you even try anything yourself to find the solution? The question sure looks like a homework assignment, which is not something you'll get help for here unless you show that you've actually tried and frankly I don't believe that you have.

So do the following:
Search for 'for loop' or something similar and try to understand what it does... then if you don't understand - post here some code of what _you_ have point out exactly which part _you_ don't understand. Then we will help you
