C++11 (formerly known as C++0x) is the most recent version of the standard of the C++ programming language. After it was approved by ISO in 2011, many books have been published to embrace the updates. Here are THREE core books that I recommend: one language tutorial, one library tutorial, and one bible.
Although it is called “primer”, this book is actually written for both beginners and experienced C++ programmers. The 5th Edition is fully updated and recast for C++11 standard as well. As a real tutorial of C++ programming language, it provides authoritative and comprehensive introduction to C++11. Another highlight is its huge amount of examples to help readers learn and understand the language fast.
