Answer 1

You're the one learning it, so it's up to you to read, learn, and practice it. When you're learning it, you're given plenty of examples and explanations for it, so I can do no better than that.

As John said, try out what you've learned or are having trouble understanding, and if you run into specific problems, come ask us and we'll be more than happy to help you out. We're not here to learn or write your programs for you though.

Answer 2

You're asking a lot. You should code what you think is a good example of it and ask if you're right.
