C++ Advanced: Move Semantics and Concurrency

Lesson Promise

By the end of this lesson, you will understand how move semantics eliminates expensive copies by transferring ownership, and how C++ threads, mutexes, and atomics enable safe concurrent programming.

Narration Draft

"C++ move semantics lets you transfer ownership of a vector's underlying buffer instead of copying a million integers — one pointer assignment instead of a million memory writes. And C++11 threads let you run code in parallel, but shared mutable state means you need mutexes and atomics to avoid race conditions. The STL gives you all of this in standard library form."

Visual Sequence

1. Scene 1 — Copy vs move: copying a vector element by element vs transferring the buffer pointer
2. Scene 2 — Race condition visualization: two threads incrementing a shared counter
3. Scene 3 — Mutex locking: thread blocks waiting for the lock, then proceeds
4. Scene 4 — Atomic operations: fetch_add, compare-and-swap
