As cute as your comment is trying to be, most languages cannot be learned by blindly trying things out, one should actually read a few books, try to be a part of the community and so on.
Take the C++ that's used on Chrome and compare to a Qt application. They'll be very different, and some features will be outright forbidden, depending on the codebase (for instance, Qt doesn't use copy constructors, or exceptions, and uses its own smart pointer classes). Not even templates, if you are using QObjects.
I know of noone that uses features such as RTTI.
Chrome and Qt's standards and design choices are their business and do not mean there is no recommended way to do things.

Note that they are both quite expensive. I am a student and it is not nothing to pay for this books.
Abe Books ( http://www.abebooks.com/ ) provides a good place to look for used copies of books. A significant portion of the books in my library have stamps on the pages indicating that they were discarded from really nice institutions.
Of course there are always free-to-read blogs, but unfortunately, good C++ blogs are harder to find than other, newer language blogs.
Effective Modern C++ is about the new C++11 and C++14 standards. I am reading it now, looks good so far.
If you can get one thing, maybe Stroustrup's book would be the best choice, but make sure you get the latest edition which includes C++11. Note that amazon.fr has the kindle versions at significant discount (there's also a bundle of Meyers' first three books) if you are ok with their DRM.
