What are some examples of using async in C++14?

Can you give me some examples of using async in C++14?

Sure! In C++14, you can use the std::async function to run tasks asynchronously. For example, you can launch a task like this: std::async(std::launch::async, [](){ return 42; });.

What does std::launch::async do?

std::launch::async ensures that the task is run on a new thread, allowing it to execute concurrently with other tasks.

Can I use async with lambda functions?

Yes, you can! Lambda functions are a great way to define the task you want to run asynchronously. Just pass the lambda to std::async.

Are there any limitations to using async?

Yes, there are some limitations, such as potential overhead from thread management and the need to handle exceptions properly.
