I was browsing around the web looking for C++ tutorials and I found The Game Institute. I have been thinking about taking their course-
C++ Programming for Game Developers - Module I - Introduction to C++ Programming Basics.
I can't imagine a Game Developers course for intro to C++ would be any different than any other intro to C++ course. There's plenty of online tutorials out there...like the ones mosta posted, but if you're looking for a class on it, I'd say only take that class if it's not any more expensive than any other intro to C++ course.
