I'd go with http://www.amazon.com/Reference-Manual-Samuel-P-Harbison/dp/... (non-aff link) for reference and something like one of these (non-aff links) for learning:

I may be using the word 'modern' a bit liberally here, but these are all more recent than K&R at least. 'C A Reference Manual' I think is what a lot of people really want out of a C book and 'Expert C'/'C Traps and Pitfalls' both help with all of the less intuitive parts of the language that you don't really get out of K&R.

For learning C I strongly recommend C: A Reference Manual (Harbison and Steele), not K&R. Read K&R for context, sure, but Harbison and Steele is more up-to-date and comprehensive while still a concise language reference. That book can basically answer almost any question about the language standard that isn't compiler-specific.

I highly recommend _C: A Reference Manual_ by Harbinson and Steele. It has many tiny examples, but it is mainly used as a reference manual (as the title suggests).

A good book for learning C is _Mastering Algorithms with C_ by Loudon. The source code is over-commented and contains too much white space, which is a bit annoying, but the content is quite nice.
