How can I use the C++ thread library for multithreading?

You can use the C++ thread library by including the <thread> header and creating threads using std::thread.

Can you show me a simple example of creating a thread?

Sure! 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 does the join() function do?

The join() function blocks the calling thread until the thread represented by the std::thread object has finished executing.

Are there any potential issues with multithreading?

Yes, multithreading can lead to issues like race conditions, deadlocks, and resource contention if not managed properly.
