What are the new concurrency models introduced in C++20?

What are the new concurrency models introduced in C++20?

C++20 introduces several new concurrency features, including coroutines, which allow for asynchronous programming, and the new synchronization mechanisms like std::latch and std::barrier.

Can you explain how coroutines work in C++20?

Sure! Coroutines in C++20 allow functions to suspend execution to be resumed later, enabling more efficient asynchronous programming without blocking threads.

What are std::latch and std::barrier used for?

std::latch is used to block a thread until a certain number of operations have completed, while std::barrier synchronizes a group of threads at a certain point in their execution.

How do these features improve performance in C++ applications?

These features improve performance by allowing better resource management and reducing the overhead of thread management, leading to more responsive applications.
