Can I use std::async instead of thread pool?

Can I use std::async instead of a thread pool in my C++ application?

Yes, you can use std::async to run tasks asynchronously, but it has different characteristics compared to a thread pool.

What are the main differences between std::async and a thread pool?

std::async creates a new thread for each task, while a thread pool reuses a fixed number of threads for multiple tasks.

Which one is more efficient for handling a large number of tasks?

A thread pool is generally more efficient for a large number of tasks, as it reduces the overhead of creating and destroying threads.

Are there any scenarios where std::async is preferred?

Yes, std::async is preferred for simpler use cases where you want quick and easy asynchronous execution without managing threads.
