What is the difference between thread join and detach in C++?

What is the difference between thread join and detach in C++?

In C++, join and detach are methods used to manage threads. join waits for a thread to finish, while detach allows it to run independently.

Can you give me an example of when to use each?

Sure! Use join when you need the result from a thread before continuing, and detach when you want the thread to run in the background.

What happens if I forget to join a thread?

If you forget to join a thread, it can lead to resource leaks or undefined behavior, as the thread may still be running when the program exits.

Are there any performance implications between the two?

Yes, detach can be more efficient for background tasks, but it requires careful management to avoid issues like accessing invalid memory.
