How do async C++ and async Python compare?

What are the main differences between async C++ and async Python?

Async C++ typically uses libraries like Boost.Asio for asynchronous operations, while async Python uses the asyncio library. C++ is generally more complex due to manual memory management, whereas Python's syntax is simpler and more user-friendly.

Which one is better for high-performance applications?

C++ is often preferred for high-performance applications due to its lower-level control and efficiency. However, Python's async capabilities can be sufficient for I/O-bound tasks and rapid development.

Can you give an example of async code in both languages?

Sure! In Python, you might use async def to define an async function, while in C++, you would typically use std::async or a similar construct. Would you like to see specific code snippets?

Yes, please provide code snippets for both!

Here's a simple example in Python:

import asyncio

async def main():
    print('Hello')
    await asyncio.sleep(1)
    print('World')

asyncio.run(main())

And in C++:

#include <iostream>
#include <future>
#include <chrono>

void hello() {
    std::cout << "Hello" << std::endl;
    std::this_thread::sleep_for(std::chrono::seconds(1));
    std::cout << "World" << std::endl;
}

int main() {
    std::async(std::launch::async, hello);
    return 0;
}
