What are some examples of concurrency in C++?

Can you give me some examples of concurrency in C++?

Sure! Concurrency in C++ can be achieved using threads. For example, you can use the <thread> library to create multiple threads that run simultaneously.

How do I create a simple thread in C++?

You can create a thread by including the <thread> header and using the std::thread class. Here's a simple example:

#include <iostream>
#include <thread>

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

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

What about using mutexes for thread safety?

Great question! You can use std::mutex to protect shared data. Here's a quick 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;
    return 0;
}```
