Complete Modern C++ - Task-Based Concurrency - Part I

The video tutorial explains how to create and manage threads in C, focusing on both low-level and high-level concurrency. It introduces the concept of task-based concurrency, where tasks are executed in separate threads without direct thread management. The tutorial also covers the use of literals and function invocation in C, particularly with C-14. It further explains the use of the async function for executing tasks, highlighting the importance of handling the future object returned by async to avoid blocking the main thread.

What is the primary benefit of low-level concurrency in C?

• It enhances the readability of the code.

• It provides more control over thread management.

• It simplifies the code structure.

• It automatically manages memory allocation.

In high-level concurrency, what are functions executed in separate threads called?

• Tasks

• Modules

• Threads

• Processes

What was introduced in C-14 that is mentioned in the context of function invocation?

• Memory management functions

• New data types

• Literals

• Enhanced loops

What is the role of the async function in task-based concurrency?

• It manages memory allocation for tasks.

• It creates a new process.

• It executes a function as a task in a separate thread.

• It synchronizes multiple threads.

Why is it important to capture the object returned by async?

• To automatically manage thread priorities.

• To enhance code readability.

• To ensure the main thread does not block.

• To prevent memory leaks.

What type of object does async return?

• Promise

• Thread

• Task

• Future

What function is used to make the main thread wait for a task to finish?

• pause()

• join()

• wait()

• get()
