What are race conditions in C++?

What are race conditions in C++?

Race conditions occur when two or more threads access shared data and try to change it at the same time.

Can you give me an example of a race condition?

Sure! Imagine two threads incrementing a shared counter without proper synchronization. They might read the same value and both increment it, leading to incorrect results.

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.

What are the performance implications of using locks?

Using locks can lead to performance overhead due to context switching and potential deadlocks if not managed properly.
