What are the consequences if two threads operate on the same memory area simultaneously?

When two threads operate on the same memory area without proper synchronization, a race condition occurs. This leads to unpredictable program behavior, such as:

• Data corruption, when one thread overwrites data written by another.
• Data integrity violations, especially during concurrent read/write operations.
• Hard-to-reproduce bugs that manifest irregularly and depend on thread execution order.

To prevent these issues, synchronization mechanisms like mutexes, semaphores, atomic operations, and other tools are used to ensure exclusive access to shared resources.
