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

Multithreaded Summation: Using Atomic Variable

Explore how to implement multithreaded summation of a vector using atomic variables in C++. Understand why atomic operations can outperform lock-based synchronization. Learn to use atomic fetch_add and += operators to optimize concurrency in summations.
