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 of a thread before continuing, and detach when the thread can run on its own without needing to synchronize.

What happens if I forget to join or detach a thread?

If you forget to join or detach a thread, it can lead to a resource leak or a program crash, as the thread may still be running when the main program exits.

Are there any best practices for using threads in C++?

Yes, always ensure to join or detach threads, avoid sharing mutable data without synchronization, and prefer using higher-level abstractions like std::async when possible.
