Title: code in CD is not well written with a massive class for the
Product review: The book is not much more useful than previous editions for Fortran and C in 1986 edition. The C++ code is written under a common class defination "nr.h" for the whole book, which is a very bad idea. The "nr.h" is massive, hard to examine any attributes, hard to be portable and visualize the code for each method. It is very bad idea!! It appears that the authors are trying to tie-up user to buy book and CD all together. The authors did not think for people to use it conveniently. It is not worth to buy the book and the CD. The code is not useful and you have to re-write them.If the Authors write the C++ code in such a manner that each method is self-contained, portable, easy to understand and use, it would be a different book and useful.
