This is truly the best lecture. Personally, I have watched introductory books and YouTube lectures related to C++. Since I already knew the basic C++ grammar, I was worried about whether to take this lecture or not. However, after completing the lecture, I think it was the best choice. This lecture was able to organize the C++ contents that I knew in a somewhat jumbled manner clearly and concisely. I highly recommend it to those who are just starting out with C++. I also recommend it to those who have read the basic books on the market. I would like to thank instructor Rookiss for uploading such a great lecture. Lastly, I know that you are at home due to COVID-19. Please upload the next lecture quickly. I feel dizzy.
