In the off chance that someone sees this that needs the help I've been needing... I had been searching, trying to figure out why I was getting this strange behavior with my while(scanf). Well, it turns out that I had while (scanf("%s\n", string) > 0). The editor I am using (Atom) automatically put a "\n" in my scan, with out me noticing. This took me hours, and luckily someone pointed it out to me.
