How to do it...

In this recipe, we will learn how to create two worker threads that run concurrently.

1. In your ~/test working directory, create a subdirectory called threads.
2. Use your favorite text editor to create a threads.cpp file in the threads subdirectory. Copy the code snippet into the threads.cpp file: 

#include <chrono>#include <iostream>#include <thread>void worker(int index) {  for (int i = 0; i < 10; i++) {    std::cout << "Worker " << index << " begins" << std::endl;    std::this_thread::sleep_for(std::chrono::milliseconds(50));    std::cout << "Worker " << index << " ends" << std::endl;    std::this_thread::sleep_for(std::chrono::milliseconds(1));  }}int main() {  std::thread worker1(worker, 1);  std::thread worker2(worker, 2); worker1.join(); ...
