How do I use C++20 coroutines?

C++20 introduces coroutines, which enable writing asynchronous code more naturally using `co_await`, `co_yield`, and `co_return` keywords. Coroutines allow functions to suspend execution to wait for some work to complete, which can improve performance for I/O-bound tasks.

Using C++20 Coroutines

Here's a simple example demonstrating how to use coroutines in C++20:


        #include <iostream>
        #include <coroutine>

        struct simple_coroutine {
            struct promise_type {
                simple_coroutine get_return_object() { return {}; }
                auto initial_suspend() { return std::suspend_always{}; }
                auto final_suspend() noexcept { return std::suspend_always{}; }
                void unhandled_exception() { std::terminate(); }
                void return_void() {}
            };

            bool resume() {
                // Logic to resume the coroutine
                return true;
            }
        };

        simple_coroutine my_coroutine() {
            std::cout << "Hello, ";
            co_await std::suspend_always{};
            std::cout << "World!" << std::endl;
        }

        int main() {
            auto coro = my_coroutine();
            coro.resume(); // Prints "Hello, "
            coro.resume(); // Prints "World!"
            return 0;
        }
