What are the key features of C++20 coroutines syntax?
C++20 introduces coroutines, allowing asynchronous programming with a simpler syntax. Key features include 'co_await', 'co_yield', and 'co_return'.
Can you explain how 'co_await' works in coroutines?
Sure! 'co_await' is used to suspend the execution of a coroutine until the awaited operation completes, making it easier to write asynchronous code.
What is the difference between 'co_yield' and 'co_return'?
'co_yield' is used to produce a value and suspend the coroutine, allowing it to be resumed later, while 'co_return' is used to return a final value and end the coroutine.
Are there any performance benefits to using coroutines?
Yes, coroutines can improve performance by reducing the overhead of thread management and allowing more efficient use of resources in asynchronous programming.
