C++20: The Concurrent Future

Explore the advanced concurrency features introduced in C++20. Understand atomic smart pointers, extended futures for composable tasks, synchronization primitives like latches and barriers, coroutines for cooperative multitasking, transactional memory concepts, and task blocks following the fork-join model. This lesson helps you grasp how C++20 enhances concurrent programming by addressing previous limitations and introducing new synchronization and task management tools.
