Sorry, but that’s not really how this works. We can’t just do your homework for you.
The best advice I can give you is to break your problem down into smaller steps and take those steps on one at a time. Don’t try to do everything all at once. Which small step are you stuck on?
You’ll also need to get into the habit of debugging your code. Which line of code is behaving differently from what you expected?
If all else fails, then you can post a small example program here, along with a more specific technical question. Good luck.
Please read the following guidelines and then post a more specific question if you want some help.
