How can I fix race conditions in my code?

How can I fix race conditions in my code?

Race conditions occur when multiple threads access shared data simultaneously, leading to unpredictable results. You can fix them by using synchronization techniques like locks, semaphores, or by designing your code to avoid shared state.

What are some common synchronization techniques?

Common synchronization techniques include mutexes, semaphores, and condition variables. Each has its use cases depending on the problem you're solving.

Can you explain how to use a mutex?

Sure! A mutex (mutual exclusion) allows only one thread to access a resource at a time. You lock the mutex before accessing the shared resource and unlock it afterward to ensure that no other thread can access it simultaneously.

What happens if I forget to unlock a mutex?

If you forget to unlock a mutex, it can lead to a deadlock situation where other threads are blocked indefinitely, waiting for the mutex to be released.
