I am using C++. I think maybe I might be interested in buying a book on the C++ Standard library. I couldn't find anything recent just : The C++ Standard Library, a tutorial and reference, 2nd Ed (2012) - Nicolai M Josuttis. This is not for the most recent version of C++, it is for 11 not 14.
Is it recommended that I purchase it if I am programming recent C++ (learning 14), or should I just find a website and learn from there?
Get 'The C++ Standard Library, a tutorial and reference', 2nd Ed (2012) - Nicolai M Josuttis. It is currently he best book for learning about the standard library.
