   Game Development Career Demo?
  I'm looking to break into the Game Development industry in the near future and I need some advice as to how to go about it. I've browsed a few job finding sites for game programming jobs and a lot have mentioned that an understanding of C++ is essential, ie a demo of some sort. I'm just wondering what kind of demo would be sufficient to make a good enough impression on possible employers. If people have any demos that they sent off when getting into the field that they can show to me so I have a rough idea of the complexity that the demo needs to be.I've been working through a few books on C++ and Game Programming using C++ which features example games to code. One of the games is a game where you control a motorbike and have to jump over a row of cars, daredevil-style, ensuring you land safely on the end ramp. You have to use the correct speed to land safely otherwise you end up hitting the cars or jumping too far and crashing into the floor. Would this be suitable? Any and all info would help.   
  That should be a decent demo.  But it better be your own work.  You will run into big problems down the line if you use a sample out of a book as your own demo.If you are short on good relevant experience (which it sounds might be the case), a good impressive demo will be essential.  When you have more experience, it matter less.  All it's really good for is getting your foot in the door for an interview.  So until your resume is really hot, the demo will have to fill in and showcase your abilities.A good demo should show good coding style (documentation, etc) as well as how you approach a hard problem.
