Start programming. Best way regardless of language. Grab some examples off the web to get some basic concepts in your head and start with a simple Hello World program, and keep building up little programs with more functionality.
If your completely new to programming then you may want to pick up a book to start with, but I don't have any specifically to recommend.
If you are just new to C++, then just jump in, come up with a reasonably simple program to write and do it.
Then again, it ultimately depends on what kind of learner you are. Some people absolutely need a textbook to get going, others do best when they just jump in and actually try to do something (I think most programmers fall in that category). Some people find a classroom lecture is required before they start to get it. Figure out which type you are and approach it from that way, but if you are "do it to learn it" type, then don't get hung up on looking for a good book or tutorials or even a boatload of examples. Just jump in and write something.
