C++14: Async vs Threading

What are the main differences between async and threading in C++14?

In C++14, async allows you to run tasks asynchronously, while threading creates separate threads for concurrent execution.

Can you give me an example of using async in C++14?

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

When should I prefer async over threading?

Use async when you want to run tasks without managing threads directly, especially for I/O-bound operations.

Are there any performance considerations I should be aware of?

Yes, async can introduce overhead due to task management, while threading can be more efficient for CPU-bound tasks.
