What are some industries that require C++ devs

I am in my senior year and I am trying to make myself more attractive on a resume. By the time I graduate I want to have a couple more projects to show off. My interest is mostly in Game Programming and Graphics. I understand games isn't the easiest thing to get into, which is why I started learning graphics. Graphics is probably my biggest interest at the moment, but it may come down to me getting any other job as I develop my graphics skills.

What are some other industries and technologies that require C++ devs that I can do in the meantime? Are there any specific skills or technologies I should consider picking up and adding to my resume? What would you do if you were me?
