I took a C language class at school and wanted to review it again, but I didn't have enough time, so I looked for a compressed lecture and found this lecture. It's really compact, but it contains rich content, and it was good because it told me what to study when I couldn't decide on a direction for my studies. It organized the overall content while explaining it in an easy way, and many parts that were unclear were resolved through this lecture. I recommend it to those who have some basic knowledge but are lacking in some areas or who want to organize everything once!
