The C++ Standard Library expanded and evolved massively between C++98/03 and C++11. It's easy to forget the magnitude of these changes, because they happened gradually and sometimes invisibly. Some things (like shared_ptr, regex, and function) were developed in Boost in the early 2000s, before making their way into TR1 in 2005 and then C++11. Other things, like container move semantics, automatically improve programs without human intervention. Sometimes I can hardly believe that programmers used to live without non-intrusive deterministically reference-counted smart pointers! We are fortunate to live in such an advanced and enlightened age.
In this presentation, I'll explore how some of the C++11 Standard Library's magic works, including how the Standardization Committee fixed pair's constructors (I bet you think that pair is the simplest type in the world - ha! wrong!) and how I saved a million zillion bytes of memory across all the programs using VC10+'s make_shared<T>().
Oh, and I will also reveal a secret that has never been announced before.
