hmm, I think my question is fine how it is. I want to learn C, I am asking HN their opinion of a book I am thinking about. If you want specifics, I would revise my question to something like "I really want to learn how to reverse engineer malware so I'm starting this goal by learning C, is K&R a good resource to learn C from?"
Depending on the age and quality of the code OP is reverse engineering, learning a very modern style of coding might somewhat oppose OPs goal.
I'd advise OP to rephrase the question to something like "I really want to learn how unixv6 works as a retro computing hobby project and I want to know what books the authors of unixv6 originally read to learn C". Or "I want to eventually be able to reverse engineer stereotypical 90s/00s microcontroller code so I want to know what textbooks an average EE used to learn C in that era"
