C project

There are two levels of questions. You are required to select two questions from each level – a total of four questions.
You are allowed to use only LinkedLists.cpp (Attached)
I also need a well written explanation for the project in a PowerPoint file, with pictures of the project so I could present it.
The chosen questions that we will be working on are:
Level 1
Level 2
I will provide you with source code (LinkedLists.cpp) once I accept your bid.
