(((Course Review))) Thank you so much for making such a great lecture. I wake up early in the morning because I want to study quickly. I always felt frustrated even after reading several books that are more than introductory to C/C++, data structures, and algorithms. 1. So how do I use this code? 2. Where is the memory space of this code? 3. I know the hardware structure diagram, but what process and path does it take to get the result? It feels so good to learn about things I only knew abstractly while taking the lecture. I bought most of the lectures. (I will certify after completing all of them^^) Based on my experience of studying by myself, I am sure that if I had not taken the lecture, I would have gone through trial and error for at least a year. (((Question)))) I only looked for the necessary parts in the C introductory lecture, 1. Data structures, operating systems 2. C that I read and reflect on -> C++ ->System Programming 3.Network I plan to study in this order, supplementing the parts I lack. I wonder if there is a part that you recommend doing a mini-project like this at some point!
