Can you explain advanced threading examples in C++11?

Sure! C++11 introduced several features for threading, including the std::thread class. Would you like to see an example?

Yes, please provide an example of using std::thread.

Here's a simple example:

#include <iostream>
#include <thread>

void printHello() {
    std::cout << "Hello from thread!" << std::endl;
}

int main() {
    std::thread t(printHello);
    t.join(); // Wait for the thread to finish
    return 0;
}

This creates a thread that runs the printHello function.

What about using mutexes for thread safety?

Great question! You can use std::mutex to protect shared data. Here's an example:

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

std::mutex mtx;
int sharedCounter = 0;

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

int main() {
    std::thread t1(increment);
    std::thread t2(increment);
    t1.join();
    t2.join();
    std::cout << "Final counter: " << sharedCounter << std::endl;
}

This ensures that only one thread can modify sharedCounter at a time.
