What is the difference between async and thread in C++?

Can you explain the difference between async and thread in C++?

Sure! In C++, a thread is a separate path of execution, while async is a way to run tasks asynchronously without managing threads directly.

How does async handle tasks differently than threads?

Async allows you to run tasks in the background and retrieve results later, while threads require more manual management of execution.

Which one is better for performance?

It depends on the use case. Async is generally easier to use and can be more efficient for I/O-bound tasks, while threads may be better for CPU-bound tasks.

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

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