How can I prevent data races in my application?

What are data races and why are they a problem?

Data races occur when two or more threads access shared data simultaneously, and at least one thread modifies it. This can lead to unpredictable behavior and bugs.

How can I prevent data races in my application?

You can prevent data races by using synchronization mechanisms like mutexes, semaphores, or by designing your application to avoid shared state.

Can you give me an example of using a mutex?

Sure! In C++, you can use std::mutex to lock a section of code that accesses shared data, ensuring that only one thread can access it at a time.

Are there any tools to help detect data races?

Yes, tools like ThreadSanitizer and Helgrind can help detect data races during development by analyzing your code.
