Practicing C++20 Coroutines for Asynchronous Programming

Asynchronous programming in modern C++ can feel overwhelming due to complex syntax and new execution flows. Mastering coroutines is essential for building highly responsive, non-blocking applications that scale. This text-based course helps you demystify these concepts by breaking down the mechanics of modern C++ asynchronous programming. You will transition from basic synchronous code to writing efficient, event-driven coroutines with confidence. What you will learn: Understand the core architecture of C++20 coroutines, including promises, awaitables, and coroutine handles; Implement custom awaitable types to control suspension and resumption points; Manage memory safely within asynchronous execution contexts; Write clean, non-blocking code for event-driven applications; Debug common coroutine lifecycles and avoid resource leaks. We begin with foundational definitions, comparing traditional execution models to coroutines, before moving step-by-step through custom promise types, co_await, co_yield, and co_return. This course is designed for intermediate C++ developers who are new to asynchronous coroutines and want a clear, conceptual foundation without any complex prerequisites. Start reading today to write efficient, modern asynchronous C++.
