C++ Thread Synchronization Tutorial | Mutex Explained with Example (Before & After Code Demo)

Want to understand thread synchronization in C++? In this video, I demonstrate how running multiple threads without protection leads to inconsistent, abnormal, and unexpected results.
Then I fix the issue using a mutex to safely access a shared resource.

This tutorial is perfect for:
✔ C++ beginners
✔ Students learning multithreading
✔ Anyone preparing for coding interviews
✔ Programmers who want to understand race conditions & mutex usage
