“Everyone with a degree in Computer Science,” then. You taught yourself and that’s great, but you have to accept you might have missed something along the way. Avoiding goto and seeing how if/else is normally handled is CS1 stuff. … Although goto is used so rarely outside ChoiceScript these days that it’s probably also a viable strategy for the instructor to pretend it doesn’t exist.
I also want to point out that I actually teach CS for a living at Northeastern University, and when I was working at Google instead for a few years, I became certified to review others for style issues. So while you should be proud of your accomplishments in this sphere, I think you should also probably believe me when I say that there is an accepted wisdom on the general principles I’m talking about.
