c++ zybook errors

Hello there I completed one project through zybooks, but the code is presenting some errors the project has 3 parts and they are all presenting errors which are listed below.
The main.cpp is a read file only as well as other files the only file that can be modified or changed is the LinkedList.h. We will work remotely through my computer, teamviewers
