writing an interpreter for a simple language

[eyalkz]

Hi Everybody,

I need to write a simple interpreter (in C) for a very Simple language...
the language (was invented for the project) has only

variable or numbers (there are also built-in variables)
routines and expressions (routines can have recursion )

where can I find help and source code on that project...?

I heard this assignment is often given to students on programming courses...

Please Help,
Egal Konn

Try using YACC to generate your interpreter since you want it in C.

Books on compilers should describe how to write parsers, which are the most
important part. You might also look to lex/flex and bison/yacc, tools to
make parser writing easier.
