Multithreaded Summation: Using std::lock_guard
Explore how to safely sum elements of a vector using multiple threads in C++ with std::lock_guard. Understand the synchronization overhead involved, compare it with atomic operations, and evaluate performance differences against single-threaded summation.

You may have already guessed that using a shared variable for the summation with four threads is not optimal; the synchronization overhead will outweigh the performance benefit. Let me show you the ...
