As a major, embarrassingly, since I only focused on C/C++, I knew absolutely nothing except C, but thanks to watching this lecture, I was able to pass the first practical exam of '25. Additionally, the difficulty of the code section in this exam seemed harder compared to previous questions, so I thought it was important to secure points in the theory section, and thanks to the materials summarizing the theory section provided as an appendix, I was able to secure points. Since my graduation project schedule overlapped with various personal schedules, I thought I would just take this exam for the experience, but discovering and taking this lecture two weeks before the exam seems to have been the best decision of the year!!
