What are the differences between threading and asynchronous programming in C++14?

In C++14, threading allows multiple threads to run concurrently, while asynchronous programming enables non-blocking operations.

Can you give me an example of threading in C++14?

Sure! You can use the <thread> library to create threads. For example:

#include <thread>

void function() {
    // Code to run in a thread
}

int main() {
    std::thread t(function);
    t.join(); // Wait for the thread to finish
}

What about an example of asynchronous programming?

In C++14, you can use std::async for asynchronous tasks. Here's a simple example:

#include <future>

int asyncFunction() {
    // Some long-running task
    return 42;
}

int main() {
    std::future<int> result = std::async(asyncFunction);
    // Do other work...
    int value = result.get(); // Get the result when ready
}

Which one is better for performance?

It depends on the use case. Threading can be more efficient for CPU-bound tasks, while asynchronous programming is better for I/O-bound tasks.
