I last touched upon C++ a few years ago and since then most of my professional work has been in C#. As I'm looking to move country and gain a new career I'm wanting to freshen up my C++ knowledge and skillset.

Can someone recommend the best place on the web, or a book, that I may be able to learn the new C++ standards that have been put in place since I last used it?

If you are not a beginner of the programming in general, i can suggest the one made by the creator of c++: c++Book. I've started with that.

From the master himself:

http://www.stroustrup.com/C++11FAQ.html

Doesn't look very stylish, but it's a very good introduction. It also explains the motivation for some changes, e.g. rvalue references (in my opinion the most important C++11 language feature).

Yes, of course, i bought it in May and i'm very satisfied....
