C Language as Learned by Following Hong Jeong-mo

I have completed the course, but I am writing a review now. I am a non-major computer engineering master's student who studied the course. I am writing this review with the hope that it will be helpful to those who are considering taking the course and with gratitude to the professor. I would like to summarize it first, saying that you should not hesitate to take this course. As I mentioned above, I took the course without knowing anything about programming or computers. I really liked the professor's ambition to create lectures on YouTube. "People who have taken my lectures can trust and work together" (I wonder if that is accurate... maybe it is embellished?) I would recommend that you take this course even if you do not have basic knowledge. This is because the lecture proceeds with the lecture by first explaining the contents that may be confusing later (memory association, operating system operation, etc.). Later, the pointer part, which may seem difficult at first, will be mentioned several times, dozens of times in advance in the pointer lecture. I think you don't have to worry. --Impressions on additional learning after completing the C language course-- It took me two weeks to complete the course. I kept up with it. Two weeks later, I went to take a computer science and C++ language seasonal language course. I will take the final exam tomorrow (Monday), but my midterm grades are in the top tier. I was able to proceed with C++ without any difficulties (of course, if I got stuck in the logic part, it would be a problem, but in terms of grammar and understanding). (In fact, I was helping undergraduate students who were majoring in it.) I am slowly taking the necessary parts of C++, starting with object-oriented language, but I personally recommend taking the C language course and then approaching C++. My opinion is that if you have mastered C and C++ to a certain level, you don't have to worry about other languages. I am also learning Python because I am greedy, but most of the content is skippable, and if it is short, you can learn other languages in a few hours or days. After all, when you learn a low-level language and then approach a high-level language, you feel like, "What's so easy?" It felt like I was releasing a sandbag after exercising. For those who hate writing in a long paragraph... 1. I recommend C++ after C language, and you don't have to be afraid of not having a basic knowledge. (Assuming that you are completely blank, the lectures in the beginning of C language and the stories about memory and OS operation that come up here and there will help you understand.) 2. If you do Professor Hong Jeong-mo's C language properly, you will feel like C++ is just a little bit of a stretch. 3. If you learn C language/C++, you will learn other languages quickly. 4. Feedback on questions is fast. (The professor is diligent. However, you may be asked to think again, and it is up to the student to find the correct answer.) 5. He explains in relation to the field. (Please always mention how to use it, some are old and the current trend is to use it this way, some are individual differences, so it's a difference in coding style, some are right and wrong, some are still ambiguous and there is no answer, etc.) 6. If you don't mention the disadvantages, I don't trust you, so I will mention them as well. The lectures are crazy detailed. It can be an advantage or a disadvantage... It's incredibly detailed. I only listened to the lectures and looked through the book to see how it was, but you really teach everything. 7. A huge amount of lecture time and lack of lecture materials (50 hours... Most online lectures, not even college classes, don't teach like this in one semester. Especially if this is coding, you have to spend X2 hours debugging, typing lecture material code, and taking notes. As you can see from the title, you learn by following. I think it should include following along and correcting mistakes where you made a mistake.) P.S. I should have listed it in the advantages.. The tuition fee of 77,000 may be expensive, but I thought it was a seasonal class fee and bought it. And I also took a computer science class as a seasonal class, and it's different value. Rather than just going through the superficial and mediocre classes, buy it all at once! Thank you, professor. Thanks to you, I'm building a good foundation.

This is a review of the course for undergraduate students :) After studying up to the level of Pointer in the first semester of my freshman year, I enlisted in the military. Luckily, I was able to continue studying little by little in the military, and although I didn't study in depth, I did some algorithms and PS implementations that weren't too difficult. Now, I'm about to return to school in the second semester, and I wanted to learn C properly again, so I started Ttabae. Now that I've overcome all the big mountains in Ttabae and (personally) entered the later courses that aren't too burdensome, I'd like to describe my feelings. First, I'd like to recommend this course to undergraduate students. I would definitely recommend this course to undergraduate students or prospective freshmen. Not only is it worth the price, but I think the content is really valuable to undergraduate students. If you take the course in an undergraduate school, it may vary depending on the professor's personality, but I think it's basically a series of studies that are rigorous but difficult to embody easily. The professors also make constant efforts to improve the students' level, but it's really hard to lead all students to the same point. At this time, the professors' choice is to lower the level so that all students can follow, or to give up on students who cannot follow. I was lucky enough to study for one semester with a professor who did not give up on everyone, and fortunately, I was able to build a foundation to some extent. However, not all students can enjoy this kind of luck. Among the ordinary undergraduate students around me, many complain of great difficulty in the first semester classes. As a result, they end up becoming students who barely learn C grammar without properly building a foundation. This may be due to the philosophy of C, which completely trusts programmers, and it may also be due to the hardware knowledge required to properly understand C. However, I think the most important factor is the lack of time to properly embody knowledge of strict accuracy. In reality, the time given to professors and students during class is quite short to aim for embodying students, so embodying is completely left to the students. That is why I recommend this course to freshmen and undergraduates. As the title, Learning C by Following, suggests, this course encourages us to directly participate in important parts. The process of following the code and repeatedly encountering practice problems simultaneously helps you acquire and internalize the concept of C. And, here are the disadvantages. The first disadvantage is that this lecture explains a large chunk. In other words, it is not a lecture that explains A in the beginning, B, and then C, but rather a lecture that explains A and b, c, d, and e in the beginning, and B, C, e, and f in the end, and completes ABCDEFG at the end of the lecture. Therefore, even if you know the concept, you cannot skip the middle part and listen to the lecture. Of course, this disadvantage is not a big problem because even if it is a part that I knew exactly, I will gain something after listening to the lecture. The second disadvantage is somewhat shared with the disadvantage above. I will explain this disadvantage with an example. Now, I took notes after listening to the concept of A in the beginning of the lecture. However, the explanation is vague and confusing. At this time, in order to resolve this concept of A in this lecture, you must first listen to the reference lecture. Then, at some point, a more rigorous explanation of A appears, or other secondary explanations make you realize the identity of A clearly. This process is quite painful. It is like a sweet potato stuck in your throat, but you have no water, so you have to swallow your saliva drop by drop. However, this pain has become the driving force that keeps you listening to this lecture consistently. For almost a month since I first started listening to the lecture, I have continued to try to relieve this frustration, and now I am finally getting to the point where I can finish this lecture with a sense of relief, swallowing the sweet potato with some difficulty. This lecture is by no means an easy lecture. Rather, it is closer to a difficult lecture. However, because of that, it is a lecture that saves more time. It does not stop at simply conveying knowledge, but because Mr. Ttaebae's lecture and Mr. Hong Jeong-mo's lecture are with you through the painful time of directly embodying it, I think that in the end, you will not waste time and will go faster. I can't even imagine how much futile effort it would have taken to fill in the gaps on my own to get to this point. Therefore, I highly recommend this course :)

I completed the course in 5 months. I majored in programming, but I neglected my studies because I didn't understand and wasn't interested in what I learned in school. At one point, I realized that all of this was because my basics weren't solid. I first came across it on YouTube, so I watched the lectures and saw that the professor explained the basics thoroughly, so I signed up for the course, thinking that it would be my last attempt before giving up on programming. At first, I was thinking of doing game programming and wanted to do C++, but I heard the advice that I should learn the basics in C and move on to C so that I would have less trouble in the field later, so I ended up doing C. As I learned the basics one by one, I gradually gained confidence and interest. The lectures were good at pointing out important points and organizing them by unit. They also kept reminding students of important parts in the later lectures so that they wouldn't forget. They also showed us things that could be solved differently even if the results were the same, and helped us understand with many examples. We were able to use our study time more efficiently because we learned the basics one by one, and the important and relatively unused parts of programming well organized. The lectures pointed out important points well and organized them by unit. Also, the important parts were constantly reminded in the later lectures so that the students would not forget them. One thing that is regrettable is that although the lectures are very detailed and thorough, there are parts that I do not understand (of course, I think my understanding is a bit lacking). So I went to the previous lectures and studied again, but even then, when I asked questions about parts that I did not understand, there were sometimes answers that I did not understand clearly. However, excluding these regrettable points, I can say that this was a class that I looked for and listened to by other teachers that dramatically improved the understanding of grammar and computer memory for major students who do not even know the basics. I feel sorry that I did not pay enough for such a great lecture. Thank you so much for the great lecture. I will now go take Professor Hong Jeong-mo's C++ lecture.

Although I am not a major, I started with the thought that I absolutely had to learn C as my first study. It is true that C is difficult to learn due to its characteristics, and there are many things to worry about. However, the more I listened to the lectures, the more I became convinced that learning C would be a good skill in the long run. * Lecture Features 1. Lectures that teach computers The professor teaches computers through the 'C language' in each lecture. As you study in the future, you will learn various concepts of computers, and it will help you develop the skills that you can use as a foundation. 2. Review It is good to follow the progress, but this is a lecture that requires you to review on your own. When I thought I had learned the concepts, I would always get stuck when I tried to write an example from scratch on my own. However, when I saw my skills improving as I tried to do it on my own, I realized that I definitely needed to review. * Others “Western philosophy is nothing more than footnotes to Plato.” (Whitehead) - There are many types of philosophy, but each of them had a great influence on Plato in the past in forming academic concepts. At first glance, the C language may seem like an old language, but it is the most basic and major language that created the main stem, so I think it may occupy a similar position to Plato. Thank you for the great lecture.

I heard that I have to learn C to become a great programmer. I bought a famous book and studied without understanding the purpose of C or why people tell me to learn C. I regret the past, but I am glad that I can now go in the right direction. I recommend this lecture that helped me a lot in learning C. A common saying about C is that the devil is in the details. C has a small amount of grammar, but it is not an easy language to learn. Since it gives programmers a lot of freedom, if you don't study it properly, you can fall into various traps. Also, if you don't understand computer systems first, you will have questions about the execution results of your code and you won't be able to resolve those questions. Many people, including me, study C without knowing this fact. The lecture, 'Learn C by Following Hong Jeong-mo' (Ttabae-ssi) can solve these difficulties. Based on excellent C language textbooks such as K&R, KNK, and C Prime plus, you can learn the standard of C language with certainty. Of course, it is not a lecture that is exactly as it is in the book, and there is a lot of additional content. Mr. Hong Jeong-mo, who created the lecture, has experience as a university professor and a programmer in Silicon Valley, and you can feel his inner strength. What is unique about this lecture is that it does not teach the grammar of C language right from the first lecture, but first teaches the operating principles of computers. Some of the content is also taught in computer architecture courses at universities, which is very helpful for understanding the later content. In addition, Mr. Ttaebae adopted the 'spiral learning model' in this lecture. Even after the lecture on the operating principles of computers is over, he does not only teach the grammar of C language, but also continues to explain CPU, memory, operating system, etc. little by little in the middle of the lecture. Also, since he repeatedly explains the content to be learned from the beginning to the middle and the latter part of the lecture, I was able to understand the content naturally while listening to the lecture. In addition, there were many features of Visual Studio, debugger usage, and other contents that are not covered well in regular C language books due to space constraints, which was good. I previously studied C language by reading a book alone. It was quite difficult because new concepts kept coming up in the latter half of the book. And even after reading the entire book, all that remained was grammar. On the other hand, when Mr. Tta-bae's lectures went towards the latter half, the content I had learned before was very naturally connected, allowing me to experience the puzzle of the C language being put together, and although it covered a lot of grammar, it was not a lecture where only grammar remained in my head. This is because Mr. Tta-bae's lectures do not only teach the C language. Through Mr. Tta-bae, I gained an understanding of computers and a stepping stone that I can use when learning other CS contents. As the title suggests, "Learn C language by following," I studied by following all the codes in the lectures, and although it took a long time to listen to one lecture, the content of the lectures that I have listened to once is hard to forget. I highly recommend Mr. Tta-bae to those who are studying C language for the first time, and to those who have studied C language but feel something is lacking.

While programming, I often thought to myself, "I feel like I have no foundation." While listening to this lecture, I felt like that empty foundation was filled, and my perspective on computers and programming changed. If the programming I've done so far was like being confused and dragged along every time I encountered a new problem, I think that from now on, I'll accumulate knowledge like a snowball every time I encounter a new problem and solve it. If it weren't for this lecture, I might have never filled the foundation. Thank you so much for creating such a great lecture.

It was the best lecture. The Visual Studio tips that were given here and there were also very good, and the C language grammar and coding patterns used in the field were also good. I will continue to study C++. Thank you!!
