Back to Basics: Rvalues and Move Semantics in C++

on YouTube ↗01h 00m

" summary

Implements a minimal string type and implements a minimal string with move ctor/assign showing the actual code changes and prints that prove the move happened, experiments with compiler flags to demos -fno-elide-constructors and RVO/NVRO, measures where copy elision hides moves, demonstrates when to add noexcept to moves and the concrete impact on std::vector reallocation, explains std::move vs std::forward, fixes a real pop/swap bug (avoids dangling references) and follows rule‑of‑zero/design guidance.
