What are race conditions in multi-threading?

What are race conditions in multi-threading?

Race conditions occur when multiple threads access shared data and try to change it at the same time, leading to unpredictable results.

Can you give me an example of a race condition?

Sure! Imagine two threads trying to increment the same counter variable. If both read the value at the same time, they might both increment it, resulting in a lost update.

How can I prevent race conditions in my code?

You can use synchronization mechanisms like mutexes or locks to ensure that only one thread can access the shared resource at a time.

Are there any tools to help detect race conditions?

Yes, tools like ThreadSanitizer and Helgrind can help detect race conditions during the development process.
