What are the differences between C++ async and thread pool?

What are the differences between C++ async and thread pool?

C++ async is a way to run tasks asynchronously, while a thread pool manages a collection of threads for executing tasks.

When should I use async instead of a thread pool?

Use async for simpler tasks that can benefit from non-blocking execution, while thread pools are better for managing multiple concurrent tasks.

Can you give an example of using async in C++?

Sure! You can use std::async to run a function asynchronously like this: auto future = std::async(std::launch::async, myFunction);.

What are the performance implications of using one over the other?

Async can be more lightweight for simple tasks, but thread pools can be more efficient for heavy workloads due to better resource management.
