What are some real-world examples of thread safety issues in programming?

Thread safety issues often arise in multi-threaded applications. One famous case is the "dining philosophers problem," where multiple threads compete for limited resources, leading to deadlocks.

Can you explain how this problem affects performance?

Certainly! When threads are not managed properly, it can lead to contention, where threads are waiting for each other to release resources, causing delays and reduced performance.

Are there any specific programming languages that are more prone to these issues?

Yes, languages like C and C++ are more prone to thread safety issues due to manual memory management. In contrast, languages like Java and C# have built-in mechanisms to help manage thread safety.

What are some best practices to avoid thread safety issues?

Best practices include using synchronization mechanisms like locks, avoiding shared mutable state, and employing thread-safe data structures.
