What are the new async libraries in C++14?

What are the new async libraries introduced in C++14?

C++14 introduced several improvements to the standard library, including enhancements to the async capabilities. The main addition is the std::async function, which allows for asynchronous task execution.

Can you explain how std::async works?

Certainly! std::async runs a function asynchronously and returns a std::future object, which can be used to retrieve the result once it's ready.

What are the benefits of using std::async?

The benefits include easier management of asynchronous tasks, automatic handling of thread creation, and the ability to retrieve results without blocking the main thread.

Are there any drawbacks to using it?

Yes, potential drawbacks include overhead from thread management and the possibility of exceptions being thrown if the asynchronous task fails.
