Generate a parser in c or c++ from BNF notation
Based on bison version 1.19. Compatible with bison but with C++ support. Bison is a general-purpose parser generator that converts a grammar description for an LALR (BNF-like) context free grammar into a C/C++ program to parse that grammar. Once you are proficient with bison++ you can generate a wide range of language parsers, from those used in simple desk calculators to complex programming languages.
