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:

#include <future>
#include <iostream>

int compute(int x) {
    return x * x;
}

int main() {
    auto future = std::async(std::launch::async, compute, 10);
    std::cout << "Result: " << future.get() << std::endl;
}

What does std::launch::async do?

std::launch::async is an option that tells std::async to run the task on a new thread. It ensures that the task is executed asynchronously.

Can I use std::future to get the result later?

Yes, exactly! The std::future object returned by std::async allows you to retrieve the result of the asynchronous operation later using the get() method.

Are there any other ways to handle asynchronous tasks in C++14?

Yes, besides std::async, you can also use std::thread for more control over thread management, or use libraries like Boost for additional features.
