After listening to all the lectures, I think it was a good decision to choose my first C lecture as a professor. After listening to the lecture, I felt much more free to apply and use C, and I think it became fun. Even though I am not a major, the lecture was so detailed that I became confident about the content I learned in the lecture. I am also taking C++, and it is also a very fun and interesting class. I will do my best for data structures later! Thank you for the great lecture.
