C++ Standard Template Library in Practice - Coroutines

What is a key characteristic of coroutines in C20?

• They have a single return point.

• They are only used for error handling.

• They can only be used for mathematical calculations.

• They have multiple return points and can resume execution.

Which of the following is NOT a coroutine keyword introduced in C20?

• Co_await

• Co_yield

• Co_execute

• Co_return

What is the primary difference between cooperative and preemptive multithreading?

• Preemptive multithreading requires manual thread management.

• Cooperative multithreading allows threads to run simultaneously.

• Preemptive multithreading is only used in C20.

• Cooperative multithreading relies on threads yielding control voluntarily.

What is the role of 'Co_yield' in a coroutine?

• It suspends execution and yields a result to the caller.

• It compiles the coroutine code.

• It terminates the coroutine immediately.

• It starts the coroutine from the beginning.

What is a major limitation of the C20 coroutine technical specification?

• It lacks support for any coroutine-related keywords.

• It does not specify standard coroutine abstractions.

• It only supports coroutines in Python.

• It requires a specific operating system to run.

Which library is mentioned as a third-party option for using coroutines?

• C Coro

• Boost

• LibC++

• GCC

In the practical example, what is the purpose of the coroutine code demonstrated?

• To calculate factorials.

• To generate prime numbers.

• To perform matrix multiplication.

• To sort a list of numbers.
