I finally got a semi-working version of my tic tac toe C program. I'm fairly excited as this is really the first program I've ever written (other than the “testing” programs like 'Hello, World'). It's horribly inefficient, but I'm still pretty proud of it because of how much effort I put into it. I apologize for my horrible commenting skills. Here's a link in case anyone wants to check it out: https://pastebin.com/aUunQuJx (it was compiled and tested on Manjaro GNU/Linux and Debian GNU/Hurd using the GCC)
