Just inspired me to play the snowboarding game I made in College. It's like a better version of a Tiger hand held. Dodge the trees and rocks that come flying out at you from nowhere. The teacher and lab assistant helped a lot with the game code...
I've sat in on a few entry level C++ classes but only ever completed HTML and ActionScript classes (Dreamweaver, Flash and Director), so HTML and Java. I actually enjoy programming/coding using them. Except Flash, fuck Flash.
Small tip, which explains why I didn't continue to sit in on C++ classes and which someone probably already posted, I've found whatever I'm trying to accomplish has already been done and is available online. So I'm able to take other peoples code, copy/paste it into what I'm doing, tweak it to get it where I want it and move on to the next problem.
I agree with cyber. Do it! And good luck.
