How to do it...

We will create an application that spawns two worker threads to concurrently update an array of data. Instead of mutexes, we will use atomic variables to make sure the concurrent updates are safe.

1. In your ~/test working directory, create a subdirectory called atomic.
2. Use your favorite text editor to create an atomic.cpp file in the atomic subdirectory.

3. Now, we put the required headers, and define global variables in atomic.cpp: 

#include <atomic>#include <chrono>#include <iostream>#include <thread>#include <vector>std::atomic<size_t> shared_index{0};std::vector<int> data;

4. After global variables are defined, we add our worker function. It resembles the worker function from the preceding recipes, but besides an index, it ...
