I'm finding this book to be an excellent
counter-point to Kernighan & Ritchie's book
"The C Programming Language". I think these two
books together (even though they are from different
publishers) are an excellent pairing.
Kernighan & Ritchie's provides a good, abstract
theoretical understanding of C. Oualline's book
provides the much needed practical tonic. I'm
finding that Kernighan & Ritchie give the
conceptual understanding of what C is and why it is
and Oualline provides a practical exposition of how
it works and how you should actually use that theory
that Kernighan & Ritchie lay out. I've found that
Oualline helps the Kernighan & Ritchie make sense
and the Kernighan & Ritchie helps understand the "why"
behind what Oualline says. If you've got one but
not the other and are learning C, let me suggest you
complete the set.
