How can I debug race conditions in C++?

How can I debug race conditions in C++?

Debugging race conditions in C++ can be tricky. Have you tried using tools like Valgrind or ThreadSanitizer?

No, I haven't used those tools. How do they help?

Valgrind can detect memory issues and ThreadSanitizer can help identify data races by analyzing thread interactions.

Are there any coding practices I should follow to avoid race conditions?

Yes, using mutexes, locks, and avoiding shared state can significantly reduce the chances of race conditions.

Can you give an example of using a mutex in C++?

Sure! Here's a simple example:

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

std::mutex mtx;

void print(int id) {
    mtx.lock();
    std::cout << "Thread " << id << " is running." << std::endl;
    mtx.unlock();
}

int main() {
    std::thread t1(print, 1);
    std::thread t2(print, 2);
    t1.join();
    t2.join();
    return 0;
}
