What are some effective solutions for race conditions in programming?

What are some effective solutions for race conditions in programming?

Race conditions occur when multiple threads or processes access shared data concurrently, leading to unpredictable results. Solutions include using locks, semaphores, and atomic operations.

Can you explain how locks work in this context?

Locks are mechanisms that prevent multiple threads from accessing shared resources simultaneously. When a thread acquires a lock, other threads must wait until the lock is released.

What are semaphores and how do they differ from locks?

Semaphores are signaling mechanisms that control access to a resource by maintaining a count. Unlike locks, which allow only one thread access, semaphores can allow multiple threads based on the count.

Are there any downsides to using locks or semaphores?

Yes, using locks can lead to deadlocks if not managed properly, while semaphores can introduce complexity and potential for resource starvation.
