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 two methods used with threads. join waits for a thread to finish its execution, while detach allows the thread 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, like in a calculation. Use detach when the thread can run independently, like logging.

What happens if I forget to join a thread?

If you forget to join a thread, it may lead to a resource leak, as the thread's resources won't be released properly, potentially causing your program to crash.

Are there any performance implications between using join and detach?

Yes, using join can introduce overhead since it blocks the calling thread until the joined thread finishes. detach allows for concurrent execution but requires careful management of resources.
