You must be talking about NR 2 C++ code. NR 3 code uses 0-based indexing (and it allows you to use STL vectors). It's also a lot more object oriented than NR 2 and it uses templates instead of function pointer parameters. Still, it's not very usable as a library and it's not even meant to be one. It's  basically a set of algorithms, so free functions would be better than classes, IMHO.
