What are the different techniques for ensuring thread safety in programming?

There are several techniques for ensuring thread safety, including mutexes, semaphores, and lock-free programming. Would you like a detailed explanation of each?

Yes, please explain mutexes and semaphores.

Mutexes are used to ensure that only one thread can access a resource at a time, while semaphores allow a limited number of threads to access a resource concurrently. Mutexes are binary, whereas semaphores can have a count.

What about lock-free programming? How does it work?

Lock-free programming avoids using locks altogether, allowing threads to operate independently. It often uses atomic operations to ensure data consistency without blocking.

Which technique is the most efficient?

The efficiency of each technique depends on the specific use case. Lock-free programming can be more efficient in high-concurrency scenarios, but mutexes are simpler to implement.
