What are some real-world examples of async in C++?

In C++, asynchronous programming is often used in scenarios like web servers, game development, and GUI applications. For instance, in a web server, async I/O allows handling multiple requests without blocking.

Can you give me a specific example of async in a web server?

Sure! A popular example is using the Boost.Asio library to create a web server that can handle multiple client connections simultaneously. It uses asynchronous operations to read and write data without blocking the main thread.

What about game development? How is async used there?

In game development, async is used for loading assets in the background while the game is running. For example, a game might load textures or sounds asynchronously to avoid freezing the gameplay.

Are there any libraries that help with async programming in C++?

Yes, libraries like Boost.Asio, C++11's std::async, and the upcoming C++20 features like coroutines are great for implementing async programming in C++.
