Concurrent Programming in C++
summary
C++11 concurrency features get practical coverage: std::thread plus hardware_concurrency=8 (hyperthreading can mislead), join vs detach (detached threads become daemons), and a concrete race example where 20,000 increments/decrements produce nonzero results until protected by a mutex. Shows RAII for threads, recommends lock_guard and unique_lock/std::lock to avoid deadlock, explains call_once, condition_variable, futures/async (deferred runs on caller), packaged_task and promise for exception-safe, civilized thread-to-thread communication.
