How can I use the C++ thread library for advanced topics?

The C++ thread library provides tools for multithreading, allowing you to run multiple threads concurrently. What specific advanced topics are you interested in?

I'm particularly interested in thread synchronization and avoiding race conditions.

For thread synchronization, you can use mutexes, condition variables, and locks. These help prevent race conditions by ensuring that only one thread accesses shared data at a time.

Can you give me an example of using a mutex?

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;
}

This code safely increments shared_data using a mutex.

What are some common pitfalls when using threads in C++?

Common pitfalls include forgetting to lock mutexes, causing race conditions, and not properly joining threads, which can lead to resource leaks.
