Before studying Unreal and Graphics, I felt that I lacked basic knowledge of C++. I was wondering whether to study on my own as I had been doing or to get help from a lecture, and then I happened to find Rookis's lecture. I had some programming experience and had studied C++ before, so I wondered if I should take the lecture. But now I think it was really good. I learned not only C++ grammar but also the basics of programming. I understood better when I checked the memory by opening it up, which I only knew superficially. Above all, I really liked learning how to debug. I have never seen a lecture that teaches debugging like this. I am also very much looking forward to the upcoming graphics lecture. I will quickly finish the C++ lecture, organize it, and move on to the graphics lecture.
