@luanjjjh , welcome.

Your post looks like a copy/paste of class/course assignments (advise if otherwise).
What specifically do you want help with , some/any/all ?
We are not here to do your work for you, the forum is a collaboration , you supply details about specific challenges you face - supply your attempt(s) at those and we provide guidance (that may include code) to help you get a working solution.

PS: if you have classmates/work colleagues doing same/similar, reach out to them first, having teammates to help bounce ideas off/share problems with will go a long way to helping you face challenges with confidence.
