I am an undergraduate student. I felt like I was learning a little shallowly in my department, so I was curious about things like how computers work and how coding is done(?), but I was able to learn about those things through this lecture, which was really great. This is a lecture that I would really recommend to students who want to completely understand not only the C language but also what coding is from the beginning. However, if you are completely ignorant about computer studies, it might be a little difficult. However, just trust and follow along. It will be difficult at first, but everything will be explained later, so trust and follow along. I will listen to it 2 or 3 times repeatedly and try to solve problems. The study method I recommend is not to just listen to the lecture, but to also solve assignments or problems separately. Since the lecture covers a lot of theoretical topics, I will not solve as many problems as you want. It is not a lecture about solving problems in the first place. That is why I recommend that you set aside plenty of time and take the lecture and problem solving classes at the same time. This means that you need to practice applying it. I am very satisfied with Tta-Bae C and I am going to listen to Tta-Bae C++ after listening to it all. I want to listen to all of the professor's lectures. I recommend it.
