Simple MPSCQueue with explanation

My previous post got deleted because It seems like AI detector has disliked the "polished" style of the post. I guess it should be rewritten in a more "casual" way, with grammar errors. Sorry for duplication if anyone has seen this already.

During my free time, I have stumbled upon such segment of C++ as "low latency" and "lock free". This topic has initially fascinated me so much, because I couldn't have even imagined that some thing like this could even exist, and is actively used in a very interesting and specific segment of the market... But that is a story for another time :)

I have decided to get familiar with the topic, and as my first step, I wanted to implement something. I have chosen MPSC (Multiple Producer, Single Consumer) queue, but I've quickly realised that the entry barrier is overly high. I literally had no understanding of where I could start.

I spent several weeks gathering knowledge bit by bit, studying advanced multithreading, atomics, memory ordering, and lock-free algorithms. Finally I came up with something I want to share here.

I thought it would be valuable to create a detailed walkthrough, which can be used either by me in future, when I get back to this in maybe several month or years, my friends who would love to learn about this topic, or anyone else who would find themselves in a situation like this.

This project is for sure not the best, not ideal, and not something universe-changing. It is just a "school-grader-level" project with the explanation, hopefully understandable to the same "school-grader".

I, personally, would have loved to have an article like this while I was learning, since it could save at least several weeks, so I hope it helps others in the same way.
