C language clock in the first day

This winter vacation plan to re-learn the C language. I learned it in my freshman year, but I didn’t realize its importance at that time. It was all an exam homework and I was not clear enough about my professional future. Now I feel that learning a computer language is important for communication. It is more important for professional people. So taking this winter vacation, I plan to study C language seriously again. I saw the video on station B and felt that the teacher was quite careful. I recalled some knowledge. I plan to learn one or two chapters every day in the future, and I can come here to check in every day.
