What are some common asynchronous patterns in C++?

What are some common asynchronous patterns in C++?

Common asynchronous patterns in C++ include futures and promises, async/await, and callback functions.

Can you explain how futures and promises work?

Futures represent a value that may not be available yet, while promises are used to set that value. They work together to handle asynchronous operations.

What about using std::async? How does it fit in?

std::async is a function that runs a task asynchronously and returns a future. It simplifies the process of launching tasks in a separate thread.

Are there any drawbacks to using these patterns?

Yes, potential drawbacks include increased complexity, difficulty in debugging, and the risk of resource leaks if not managed properly.
