When I was learning C++ in school this was the book we used. It's pretty comprehensive but not necessarily a step by step tutorial - the Standard C++ Bilbe

Since C++ has been around a while you might best be served by going to the library and taking home a few books, trying to figure out the best one to start with. Once you get more comfortable you may want to buy the book above. I would have to look around to find a decent online C++ resource.
