C programming.com - Learn C and C++ Programming

Or sign up for a course in your town or grab a good textbook and self-learn.

As a programmer, I'd say C and C++ were pretty tricky languages to start with. I'd suggest starting with something like Visual Basic.NET, making small programs like calculators, notepads and message boxes, then moving on to more complex programs once you understand how the syntax works. I started making "Hello, world!" message boxes and now I can make simple games, word processors and browsers. It's always useful to learn an easier event-driven programming language like VB before going into object-oriented programming languages like C, C++ and C#. It just helps you get the feel for how coding works. :)

If you still want to start with C/C++ (very good for game design) then I'd suggest C++: A Beginner's Guide by Herbert Shildt. There are also numerous tutorials on the website in the previous answer as well as the Microsoft Developer Network community and YouTube videos. :)
