What are some real-world examples of race conditions in applications?

Race conditions occur when multiple processes access shared resources concurrently, leading to unpredictable outcomes. A classic example is in online banking, where two transactions might try to update the same account balance simultaneously.

Can you give me another example?

Sure! In web applications, if two users try to book the last seat on a flight at the same time, a race condition can occur, potentially allowing both to complete the booking.

How can developers prevent race conditions?

Developers can prevent race conditions by using techniques like locking mechanisms, transactions, or implementing proper synchronization methods to ensure that only one process can access the shared resource at a time.

Are there any tools to help identify race conditions?

Yes, there are several tools like ThreadSanitizer, Helgrind, and Race Detector that can help identify race conditions during the development and testing phases.
