C++ Thread Library vs std::async

What are the main differences between the C++ thread library and std::async?

The C++ thread library provides low-level thread management, while std::async offers a higher-level abstraction for asynchronous tasks.

When should I use std::async instead of creating threads manually?

Use std::async when you want to run tasks asynchronously without managing threads directly, especially for simpler use cases.

Are there performance differences between the two?

Yes, std::async may introduce overhead due to its task management, while the thread library can be more efficient for fine-tuned control.

Can I mix both approaches in my application?

Yes, you can mix both approaches, using std::async for simpler tasks and the thread library for more complex threading needs.
