If you need to learn C, at least use the first edition of the book - the one without the ANSI additions is much smaller.
I’'ve actually never read the second/and edition so I can’t say if it is good or not. I can tell you that the first edition still has a proud space on my bookshielf though the acid paper is starting to take a toll and I suspect it won’t be long and I’ll be needing a reprint.
Yes.
