C++ 20 (2a) New Features - The Rationale Behind Coroutines

The video discusses the rationale behind using coroutines, starting with a TCP reader example from Cppcon 2015. It highlights the inefficiencies of synchronous code, especially when handling multiple connections, and the complexity of writing asynchronous code using futures. The video then introduces coroutines as a solution, showing how they simplify asynchronous code by using the co_await keyword, making it easier to read and manage.

What are the benefits of using a single thread for handling multiple connections as mentioned in the video?

Describe the role of the 'Co await' keyword in the context of coroutines.
