shared_ptr – Advanced STL, Part 1

Part 1 of my video lecture series exploring the Standard Template Library’s implementation is now available.  In this part, I explain how some of shared_ptr’s magic works, including type erasure and make_shared<T>()’s optimizations that save both space and time.


This advanced series assumes that you’re familiar with C++ and the STL’s interface, but not the STL’s implementation.  If you haven’t used the STL extensively yet, I recommend watching my introductory series.  For reference, here are all of the links:
