What are the best practices for asynchronous programming in C++?

Asynchronous programming in C++ can greatly improve performance. Key practices include using futures and promises, avoiding shared state, and leveraging libraries like Boost.Asio.

Can you explain how futures and promises work?

Futures represent a value that will be available in the future, while promises are used to set that value. You can use them to synchronize tasks.

What libraries do you recommend for async programming?

I recommend Boost.Asio for networking and concurrency, and C++20's std::async for simpler task management.

How do I handle exceptions in async code?

You can catch exceptions in the thread where the future is retrieved. Use try-catch blocks around your async calls to handle errors gracefully.
