When should I use threading or asynchronous programming in C++?

Can you explain when to use threading versus asynchronous programming in C++?

Sure! Threading is useful when you want to perform multiple tasks simultaneously, especially CPU-bound tasks. Asynchronous programming is better for I/O-bound tasks where you want to handle multiple operations without blocking.

What are some examples of CPU-bound and I/O-bound tasks?

CPU-bound tasks include complex calculations or data processing, while I/O-bound tasks involve file reading/writing or network requests.

How do I implement threading in C++?

You can use the <thread> library in C++. Create a thread by instantiating std::thread and passing a function to it.

What about using async functions?

For asynchronous programming, you can use std::async to run tasks in the background and retrieve results later.
