I decided to take this course and jump into it in earnest, with no knowledge of programming and hesitation. I graduated from an engineering school, but I only took one course in C (even that was C...) and started studying out of vague curiosity while working in a completely unrelated field. However, as I listened to the professor's lecture, I learned not only grammar but also the operating principles, so when I took other courses, the content I learned fit together like a puzzle, and I felt interested. Since the lectures are very detailed, I can quickly find the parts I want, and for someone like me who is a blank slate, I think this is a good course to learn abc and even why abc is abc. In today's trend where information is overflowing and learning quickly is the best, just like when you take drugs, you develop a tolerance and it's no longer fun, and there may be a phenomenon where you learn no matter how much you learn because you have no basics, but I think this is a good course to solve that problem. It's just the beginning, and it's been a slower process than I thought because I'm doing it while working, but compared to before taking the course when I had no idea what fields there were as a developer and what I should study, I'm proud that I've found a rough idea and gained the strength to think about the next step. I'll also persevere and finish Professor Hong Jeong-mo's C++ course, and I definitely recommend all of these courses to others.
