Introduction:
I'm currently a student, so having to pay around $60 for a ZyBook that was useless was not very clever. I was asked to finish it within 2 weeks containing 10 chapters of new material... So this is my way of saying, stop stealing money from students and make the education system better. If you have any other exercise you'd like to add to this list, leave a comment below.
The exercises below are for the book: COP 4338: Programming 3 Zybook Online.
If you are looking for the assignments, go here
Getting Stated:
Remember that they constantly update the zybook, so the answers may have been moved to another section, but the core is the same :)
