Get Sam's Teach Yourself C++ In 21 Days. It will teach you every basic there is, and is worth the $50.

quote Entropy

I would generally recommend starting with a scripting language like PHP, Perl or perhaps Python, though Python's syntax is less close to C/C++'s than PHP and Perl's. Those teach you basic programming concepts without having you worry about data types, memory management and code portability.
After that, you can start coding in C/C++, and you'll notice you already master a lot of the basic techniques and concepts.
However, you could just go for it, get a nice book, and start with C++/C if you're determined enough.

quote Vermillion

Learning it yourself won't give you bad habits, as long as you get good books, follow good recommendations, and test your own code.
Personally, I started to code two years ago. Started doing it myself, and I have yet to go to University. If you are interested, you should definitely get a head start. In that way when you go the university, you won't have too much problems understanding some concepts.

Now that you've taught yourself have you got a job out of it? Or do you actually need the formal qualifications. Been meaning to teach myself for a while, I even have the "C++ for Dummies" book upstairs but I've never got round to it.

I am just a high school student .

PHP, Perl and Python are all perfectly fine scripting languages which can be used for webapplications but can also be used for quick scripts that don't require the power of a language like C.
A lot of exploits and other small scripts that just need a socket to send some data are often written in such a scripting language. I would mainly recommend them because they're easy to learn and can quickly be picked up, whilst still forcing the user to learn important programming mechanics, like loops, arrays, condition branches, switch/case and even things like sockets and file input/output. If you have absolutely no programming experience whatsoever, that can really help you out a lot, just so you can get used to some more general stuff and are more quickly able to tackle more advanced subjects. I personally noticed I could pick up C more quickly after learning PHP. Though I was interested in web development, otherwise I may have taken the plunge and went straight for C as well.
Not saying it's a must to get some experience through scripting languages, just saying it might help.
