Query: The art must be in the algorithms, it is not in the code...

I cannot judge the algorithms and their implementations, I suppose they are good. But the code the give is absolutely horrible. Not to industrial standards at all. No matter how brilliant the content, it is the code you buy this book for. I hope they tested it thoroughly, cause it is bad.My advice to the writers: have the code rewritten using templates (STL). Just translating Fortran to C won't do on this level.
