How can I debug data races in my C++ application?

Debugging data races in C++ can be challenging. You can use tools like ThreadSanitizer or Valgrind to help identify them.

What is ThreadSanitizer and how does it work?

ThreadSanitizer is a dynamic analysis tool that detects data races in C++ programs by instrumenting the code at runtime.

Are there any best practices to avoid data races?

Yes, using mutexes, avoiding shared mutable state, and employing atomic operations are some best practices to prevent data races.

Can you give an example of using mutexes in C++?

Sure! Here's a simple example:

#include <iostream>
#include <thread>
#include <mutex>

std::mutex mtx;
int shared_data = 0;

void increment() {
    mtx.lock();
    ++shared_data;
    mtx.unlock();
}

int main() {
    std::thread t1(increment);
    std::thread t2(increment);
    t1.join();
    t2.join();
    std::cout << "Shared data: " << shared_data << std::endl;
}
