What are some practical use cases for C++20 coroutines?

C++20 coroutines are great for simplifying asynchronous programming. They can be used in scenarios like network programming, game development, and UI applications where you need to handle multiple tasks without blocking.

Can you give an example of how they improve network programming?

Sure! In network programming, coroutines allow you to write code that looks synchronous while handling multiple connections. This makes it easier to read and maintain, as you can avoid complex callback chains.

What about their impact on game development?

In game development, coroutines can manage game loops and animations more efficiently. They help in writing cleaner code for tasks like loading resources or handling events without freezing the game.

Are there any downsides to using coroutines?

Yes, while coroutines simplify code, they can introduce complexity in debugging and may have performance overhead in certain scenarios. It's essential to evaluate their use case carefully.
