Your best bet for starting to learn C++ is to just break down and buy an intro-level book for it. In my experience, most online tutorials for it are either aimed for the advanced users or just have too steep of a curve (i.e. taking you from writing a "Hello World" program to writing a raytracer...from scratch).
C/C++ is kind of a tough beast to master. Its syntax and built-ins are actually rather basic, it's all of the library functions that are a bear to learn. The advantage of an intro book is that it lets you get a feel for the language using the standard libraries. While you can't apply all of the same concepts to certain libraries (writing a game for a graphical OS is going to be very different from writing a console program, for instance) it will still give you a level of comfort with the language.
Case in point: I ended up adding a scoring system to the popular open-source DDR simulator, StepMania, a while ago. While it did prove to be much different than anything I had ever worked on (and thus, it took quite a bit of prodding around to really "get" everything), the knowledge that I had of the language made working on it much easier than it would had I been winging it.
