Modern C++ Concurrency: Get the most out of any machine

Thread-Safe Singleton: std::lock_guard

Explore how to implement a thread safe singleton pattern using std lock guard in modern C++. Understand the role of mutex and locking to ensure safe concurrent initialization and gain insight into the limitations of this approach in performance.
