What are the best practices for C++ async programming?

What are the best practices for C++ async programming?

When programming asynchronously in C++, it's important to manage resources effectively, use futures and promises, and avoid race conditions.

Can you explain how to use futures and promises?

Sure! Futures represent a value that will be available in the future, while promises are used to set that value. You can create a promise and then get a future from it.

What are some common pitfalls to avoid?

Common pitfalls include not handling exceptions properly, failing to synchronize access to shared resources, and creating too many threads.

How can I improve performance in my async code?

To improve performance, minimize context switching, use thread pools, and ensure that your tasks are lightweight and efficient.
