This lecture was really helpful for my introduction to C++. What I was particularly impressed by was that the professor not only taught the grammar of C++, but also explained the characteristics of C++ and the "conventional parts" in detail. After studying the lecture, when I saw other C++ code, I didn't think, "Why is it used like this? It seems that there is no grammatical problem even if it is not like this?" Instead, I was able to understand it easily with the thought, "Oh, this is how it is used conventionally, as I learned in the lecture." Since the conventional parts are literally conventional, there seem to be many parts that are not easy to understand unless someone explains them. The professor's lecture was really helpful because he explained these conventional parts in detail and made them understandable. I was also very satisfied with the way the lecture was conducted. Personally, I found the "learning method" I am interested in this, but when learning a vast amount of knowledge, if you learn everything at once and thoroughly from the beginning, you will usually forget the beginning part. Therefore, in this case, I think it is important to review consistently, but I think that is inefficient because the time spent on learning will increase. If you do not review consistently, you will end up forgetting important parts, and the goal will be 'completing the lecture' rather than 'learning', so you will not have much knowledge left. However, in this lecture, while telling you the important parts of each section, you also introduce other concepts related to that section in advance, and you are told, "You can skip the parts you don't understand yet. We will cover them in detail later." Therefore, if you skip the parts you don't understand in that section and focus on the parts you say are important and follow the lecture consistently, you will find yourself thinking, "Oh, this is the part you were talking about back then." When you think about it, you will experience an experience as if a puzzle is being put together. I was personally very satisfied with this lecture method. It is the same learning method I have pursued in the past. Also, when studying some knowledge on my own, even if I don't understand it right away, I had to go through the process of grasping the overall framework and distinguishing between important and unimportant parts on my own. In this lecture, the professor not only distinguished between important and unimportant parts in the section I was studying, but also had me review them, so I was able to study very efficiently. I was very satisfied. I sincerely thank you for creating such a great lecture.
