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

The video tutorial explains how to handle return values in coroutines using promises, manage exceptions, and consume values effectively. It introduces a framework for executing coroutines as concurrent tasks, ensuring each task has its own shared future instance. The tutorial also covers exception handling and provides practical examples of implementing these concepts.

What is the primary role of the 'co_return' operator in coroutines?

• To start the coroutine execution

• To return a value from the coroutine

• To handle exceptions in coroutines

• To pause the coroutine execution

Why is it important for the 'get' function in the task class to block the main function?

• To ensure the main function does not execute before the coroutine

• To prevent the main function from consuming the value before it is ready

• To allow multiple copies of the task to be created

• To handle exceptions in the coroutine

What is a shared future used for in the context of coroutines?

• To store the coroutine's return value

• To pause the coroutine execution

• To manage multiple copies of a task

• To handle exceptions in the coroutine

What does the 'wait' function do in the task class?

• It handles exceptions in the coroutine

• It waits for the future to be ready without getting the result

• It pauses the coroutine execution

• It retrieves the result of the coroutine

What does the 'ready' function indicate about a coroutine?

• The coroutine is waiting for a value

• The coroutine has passed its 'co_return' statement

• The coroutine has encountered an exception

• The coroutine has started execution
