Source code

The programs in Elements of Programming are written in a subset of C++ that is specified in Appendix B of the book. A parser written by Sean Parent for this subset is here (mirror); the header file exp_parser.hpp (mirror) contains a grammar that is very similar to the one in Appendix B.

Machines

A machine is a sequence of statements used as a component of many algorithms.
