bison/examples/c

This directory contains examples of Bison grammar files.

Most of them come from the documentation, which should be installed together with Bison. The URLs are provided for convenience.

rpcalc - Reverse Polish Notation Calculator

The first example is that of a simple double-precision Reverse Polish Notation calculator (a calculator using postfix operators). This example provides a good starting point, since operator precedence is not an issue.

mfcalc - Multi-Function Calculator

A more complete C example: a multi-function calculator.
