What are common C++ thread errors and how can I fix them?

Common C++ thread errors include race conditions, deadlocks, and resource leaks. Would you like to know more about a specific one?

Yes, tell me more about race conditions.

Race conditions occur when two or more threads access shared data simultaneously, leading to unpredictable results. You can fix them using mutexes or locks.

How do I implement a mutex in my code?

To implement a mutex, include the <mutex> header and create a std::mutex object. Use lock() to acquire the mutex and unlock() to release it.

Can you give me a code example?

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;
}
