Answer 3

You can't get answers for your question here. You show your attempt and describe what went wrong, and we will help you.

On a side note, you can find all these codes on the internet, so you could just copy paste the codes(but i won't recommend it, do them yourself because the work is given to "you")

Answer 4

Don't expect people to put effort into helping you if you're not even willing to put any effort into asking your question.
