How do I use std::thread in C++?

To use std::thread, include the <thread> header and create a thread by passing a function to it.

Can you show me a simple example?

Sure! Here's a basic 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 t.join() do?

The t.join() function makes the main thread wait for the thread t to finish executing before continuing.

Are there any potential issues with using threads?

Yes, issues like race conditions and deadlocks can occur if threads access shared resources without proper synchronization.
