How to do it...

We are implementing a simple Stack class that provides a constructor and a function named Push.

1. In your ~/test working directory, create a subdirectory called lockfree.
2. Use your favorite text editor to create a lockfree.cpp file in the lockfree subdirectory.
3. Now, we put in the required headers, and define a Node helper data type in the  lockfree.cpp file:

#include <atomic>#include <iostream>struct Node {  int data;  Node* next;};

4. Next, we define a simple Stack class. This uses the Node data type to organize data storage:

class Stack {  std::atomic<Node*> head;  public:    Stack() {    std::cout << "Stack is " <<    (head.is_lock_free() ? "" : "not ")    << "lock-free" << std::endl;    }   void Push(int data) { Node* new_node = new Node{data, ...
