shared_ptr – Advanced STL, Part 1

Visual CPP Team

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:


[STL Introduction]

Part 1 (sequence containers)

Part 2 (associative containers)

Part 3 (smart pointers)

Part 4 (Nurikabe solver) – see Wikipedia’s article and my updated source code

Part 5 (Nurikabe solver, continued)

Part 6 (algorithms and functors)

Part 7 (algorithms and functors, continued)

Part 8 (regular expressions)

Part 9 (rvalue references)

Part 10 (type traits)
