What are the differences between C++20 coroutines and threads?

What are the differences between C++20 coroutines and threads?

C++20 coroutines provide a way to write asynchronous code more easily, while threads are used for concurrent execution.

Can you explain how coroutines improve performance compared to threads?

Coroutines can be more efficient as they avoid the overhead of thread management and context switching, allowing for lighter-weight concurrency.

Are there any scenarios where I should prefer threads over coroutines?

Yes, if you need true parallelism or are working with CPU-bound tasks, threads might be more suitable.

How do I implement a simple coroutine in C++20?

You can implement a coroutine using the co_await, co_yield, and co_return keywords. Would you like a code example?
