How do I create threads in C++ using the standard library?

You can create threads in C++ using the <thread> header. Here's a simple example:

#include <iostream>
#include <thread>

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

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

What does join() do in this context?

The join() function is used to wait for the thread to finish its execution. It blocks the calling thread until the thread represented by myThread has completed.

Can I pass arguments to the thread function?

Yes, you can pass arguments to the thread function using the std::thread constructor. For example:

void threadFunction(int value) {
    std::cout << "Value: " << value << std::endl;
}

int main() {
    std::thread myThread(threadFunction, 5);
    myThread.join();
    return 0;
}
