The above is a utterly clueless post and is best ignored.
To the OP:
K&R Ansi C is one of the best book to learn "Fluent C". The code is terse, no-frills and to-the-point. It is not a "Software Engineering" book so you have look elsewhere for that. Also without an understanding of the language, its runtime services and system interfaces (eg. ABI) it is pointless to look at Security/UB and hence don't bother about it in the beginning; You can get to it later.
In summary, read K&R C along with any other books that you like.
