I am a complete beginner in programming and a self-study student, and I wanted to become a developer, so I was looking for Inflearn to learn the C language as an introductory language, and I found this lecture. After listening to the lecture, I thought it would be more efficient to have a book, so I bought a book called C Language for Self-Study, listened to the lecture, and reviewed it on my own. I was definitely able to get through the pointer concept without any problems because the book explained the basic principles in detail with pictures, so as I went through each chapter, I could think, 'Ah, so that's why it's like this'. I started from Chapter 1 and have now reached Chapter 13, and I was thinking about leaving a review after completing the course, but I think that if there are non-major beginners like me who are hesitating, I recommend studying the C language in parallel with this lecture and the Hon-gong C book. There is not much time left until the end, but thank you for uploading such a great lecture!! I will run until the end.
