It's an excellent book (see the ratings on Amazon) and also fun to read through.
C should be much easier to learn than C++. The language is much more basic feature-wise and the standard C library is very small indeed.

It's a hefty tome but that's not necessarily bad if you want to (re-)learn the language and the tricks in a proper way. Easily in my personal Top 5 books for C (The others are in no particular order: "Pointers on C", "Expert C Programming: Deep C Secrets", "The Standard C Library", "C Interfaces and Implementations".)
