What are some tips for asynchronous programming in C++?

Asynchronous programming in C++ can be quite powerful. Here are some tips: 1. Use std::async for easy task management. 2. Leverage futures and promises for handling results. 3. Be mindful of thread safety when accessing shared resources.

Can you explain how std::async works?

Sure! std::async is a function that runs a task asynchronously. It returns a std::future, which you can use to retrieve the result once the task is complete. You can specify the execution policy, like launching it in a new thread or using the current thread.

What are futures and promises?

Futures and promises are synchronization primitives. A promise is used to set a value or an exception, while a future is used to retrieve that value or exception later. They work together to facilitate communication between threads.

How do I ensure thread safety?

To ensure thread safety, use mutexes to protect shared data, avoid data races, and consider using atomic operations for simple data types. Always be cautious about how threads interact with shared resources.
