I am not a beginner, but it is ambiguous to say that I am a major, so I bought the lecture to fill in the gaps. However, fortunately, it was not difficult overall because I am a major and have learned and applied things so far. The best part of the lecture was that it started with assembly and wrote registers, and from then on, I always directly opened the memory through debugging and checked the abstract parts with my own eyes. I felt like the knowledge I already knew was becoming more concrete. Also, it is really good that the lecturer talks about not only the grammatical part but also the experience in the field and that there is a separate debugging part. And it was not boring thanks to the humor code that comes out every once in a while. If you are like me who has already majored but is ambiguous about calling yourself a major (an unskilled person who feels like your knowledge is thin or fragmented), I think you will not regret it. I gained a lot from the Modern C++ section. Thank you.
