Is that two part Java course like two different school years?
You should totally share some of your college, and personal, C++ projects!
I'm insanely paranoid about those apps that check your code for plagiarism, so I will not post any school-related stuff online. I don't want it to find one then flag is for plagiarism.
As for personal stuff, well, I've posted a couple C projects here before, if they are calculator related. Like my Kaliber Project and the HDMI video-out box, which the Pi's side is in C.
