2 Examples

Now we show and explain several sample programs written using Bison: a Reverse Polish Notation calculator, an algebraic (infix) notation calculator — later extended to track “locations” — and a multi-function calculator. All produce usable, though limited, interactive desk-top calculators.

These examples are simple, but Bison grammars for real programming languages are written the same way. You can copy these examples into a source file to try them.

Bison comes with several examples (including for the different target languages). If this package is properly installed, you shall find them in prefix/share/doc/bison/examples, where prefix is the root of the installation, probably something like /usr/local or /usr.
