Wow, thank you for such a touching review. While teaching new employees and university students, I've often wondered why C language is taught in such a difficult way that makes people give up. Pointers are certainly an important concept and essential knowledge especially for embedded systems developers, but I believe it's content that's not too late to study slowly after becoming sufficiently familiar with C. And as a follow-up to this course, I'm planning to prepare a pointers edition, which I'll also divide into basic pointers (a level that's good to know even if you're not an embedded systems developer) and advanced pointers (essential course for embedded systems developers). Although it will be a paid course, it will be an opportunity to master pointers cleanly and completely. If you get the chance, I would appreciate it if you could show interest in the pointers course as well. Once again, thank you sincerely for your touching review.
