Sorry, but Bjarne Stroustrup is certainly not for a beginner. You can check it yourself visiting his
site and browsing through the articles there. I also think that to program you would have to learn C (the native language of Windows and UNIX-like systems) together or before C++. Do not hope much on free books found on Internet. Better buy a good printed book. My personal advice is
Practical C++ Programming by Steve Oualline, O Reilly 2003. You can buy a used one on Amazon.com for as much as 2.43 USD!
