Google, honestly :/ Through a good book is likely to be always better. But do you know C? Because trust me, learning C++ without knowing C can be painful. You better first learn C, then go for C++. Also books often feature both things, with the first half about C and the second part about C++, and they also include the references for the standard library functions.
Also don't expect to be able to do wonderful things with basic C directly. The standard library only provides basic console I/O, so to do something else you'll need to use system-specific stuff. Be warned of that.
