What are some real-world examples of concurrency issues?

Concurrency issues occur when multiple processes access shared resources simultaneously, leading to unexpected behavior. A classic example is a bank account system where two transactions try to withdraw money at the same time.

Can you explain how that bank account example can lead to problems?

Sure! If two users attempt to withdraw money from the same account simultaneously, they might both see the same balance. If the balance is sufficient, both transactions could be approved, resulting in an overdraft.

Are there any other examples in different domains?

Yes! In web applications, if multiple users try to update the same record at the same time, it can lead to data inconsistency. Another example is in gaming, where multiple players might interact with the same game state, causing glitches.

How can developers prevent these concurrency issues?

Developers can use techniques like locking, transactions, and version control to manage access to shared resources and ensure data integrity.
