What is C++14's async feature?

Can you explain the async feature introduced in C++14?

Sure! The async feature in C++14 allows you to run tasks asynchronously, enabling better performance in concurrent programming.

How does it differ from the previous versions?

In C++11, you had futures and promises, but C++14 improved the async function by allowing more flexibility and better error handling.

Can you give me a simple code example?

Absolutely! Here's a basic example:

#include <iostream>
#include <future>

int asyncTask() {
    return 42;
}

int main() {
    std::future<int> result = std::async(asyncTask);
    std::cout << "Result: " << result.get() << std::endl;
}

What are the benefits of using async?

Using async can improve responsiveness in applications, allow for better resource utilization, and simplify code for concurrent tasks.
