Multi-Paradigm Programming with Modern C++ - Returning Values

The video tutorial explains how to handle return values in coroutines using promises and shared states. It covers the implementation of return values, exception handling, and how to consume these values using shared futures. The tutorial also enhances the task class with additional functions like get, wait, and ready, and discusses debugging and optimizing the coroutine framework.

What is the primary role of the coroutine promise in relation to return values?

• To execute the coroutine on multiple threads

• To manage the lifecycle of the coroutine

• To store the coroutine's return value in the shared state

• To handle exceptions within the coroutine

How does the 'get' function in the task class help in consuming coroutine return values?

• It ensures the coroutine runs on the main thread

• It simplifies exception handling

• It allows multiple copies of the task to access the future

• It prevents the main function from blocking

What is the purpose of the 'wait' function in the task class?

• To handle exceptions in the coroutine

• To wait for the future to be ready without getting the result

• To pause the coroutine execution

• To retrieve the result of the future

What does the 'ready' function indicate about the future?

• The coroutine has not started execution

• The coroutine has encountered an error

• The future is not yet created

• The future already contains a result

What improvement is suggested for the coroutine framework to enhance usability?

• Simplifying the shared state management

• Removing the need for the Co await call

• Adding more complex exception handling

• Increasing the number of executor threads
