I was originally reading the book, but then I found out there were lectures available, so I started listening to them. The book is already written in an easy-to-understand way, but after reading the book and then listening to the lectures, I understand it even better and it sticks in my head! I'm planning to read the book again after completing the lectures! I think it will feel different than when I read it the first time! I used to just vaguely memorize and use things like functions and memory management, but after learning about computer architecture, I understood why I was told to write code this way, and what role this function played! Thanks to this, I think I can better understand the code I write and write more efficient and optimized code! Thank you so much for the valuable lecture!
