Finally, I'm done! As a non-major job seeker, I thought I lacked a lot of basic computer engineering knowledge, and I started with the C language because I heard it was the most suitable language for building computer fundamentals. I'm glad that I've been able to solidify my basics by studying the C language, including memory structure, operating system, and compilation process. It's a long time, but I'm definitely learning something. Thank you to the professor for providing quality content :)
