Stroustrup's "A Tour of C++" is a great overview of C++11 and modern C++. It's not very long and worth a read to see what's new in the C++ world. The audience is aimed at people who already know C++ but want to know what's new with the latest version. I've been doing a lot more with C++11 recently and am really impressed with the language--dare I say C++ is actually fun to use.
Came here to mention this. I've also found it to be a great resource for understanding a lot of the design decisions in Rust (if you're into that sort of thing), which are often informed by similar decisions in recent versions of C++ that "Tour of C++" discusses in detail.
I don't think it's going to help that much if you're new to the language. You probably want to cram something more beginner friendly like Thinking in C++: http://mindview.net/Books/TICPP/ThinkingInCPP2e.html It's a great book that helped me really start to grok C++ long ago when I was new to the language.
I'm pretty proficient in a ton of other languages, so I'm hoping I have a pretty good head start and will be able to follow the book, but I'll read Thinking in C++ in the meantime until my order arrives. Thanks for the suggestion!
