The short review: the book is definitely worth having it.
The somewhat longer review: A surprisingly pleasant lecture for a technical book! Very practical examples.
For instance - the book teaches you how to write a C program that accepts arguments from the output of a Unix pipe "|" just after you learned about loops, Another gem would be an example about how to numerically compute the definite integral of a 1D function - for example x^3 - and this is placed before even entering into array topic. Don't worry if you don't know what an Unix pipe is - the book has an introductory chapter on operating systems in general (not just Unix) with emphasis on Unix, MacOs and MsWindows. As for the calculus example - it is pretty well explained. In fact, all the topics are in general explained in a clear manner - and it is good that some concepts, usually not found in introductory C books are mentioned and sometimes treated in depth. A chapter on debugging is included. There is also a chapter on C++.
I also appreciated the reference in chapter 13 to [...] website, which is an excellent resource (not the only one of course) for OpenGL stuff. Speaking of OpenGL, don't expect too much from the OpenGL part - it is there to highlight the C part.
My recommendation: Buy it. And if you buy this book be prepared to get dirty on your hands by working the examples.
