Try using the tutorial on this site or on another site. Also watch tutorial videos. They will help. One thing I can say is to learn how to do it right from the start so you don't pick up bad habits.
Like JohnMorris said, start with the tutorials on this site ( http://www.cplusplus.com/doc/tutorial/ ).
Work on projects while learning, because they really help you re-enforce the knowledge, and you could learn something new while experimenting! (You can find a list of project ideas here: http://www.cplusplus.com/forum/articles/12974/ and all over the web really.)
