When should I use mutexes in programming?

Mutexes are used to prevent data races by ensuring that only one thread can access a resource at a time.

Can you give me an example of a situation where a mutex is necessary?

Sure! If two threads are trying to update the same variable simultaneously, a mutex ensures that one thread completes its update before the other starts.

What are the downsides of using mutexes?

Mutexes can lead to performance bottlenecks and deadlocks if not managed properly, as they can block threads.

Are there alternatives to mutexes?

Yes, alternatives include read-write locks, semaphores, and lock-free programming techniques.
