This directory contains different grammars related to the C language:

C4.cf

A small subset of C. Used to teach programming language construction and bnfc to students at chalmers. It should be enough to parse koe2.c

C.cf

Ansi C, following Kernighan & Ritchie (Second Edition). Developed by Ulf Persson is 2003 as part of a BSc thesis at Chalmers University of Technology

C_with_delimiters.cf

Modified Ansi C grammar to make use of delimiter pragmas.

And some example programs:

koe2.c

A very simple program that prints the first 12 factorials

runtime.c

Runtime for the C4 language. Defines some "built-in" function (printX and readX). This is given to the student but serves here as an example of Ansi C program.

core.c and small.c

C examples that have been modified a bit and can now only be parsed with the C_with_delimiters.cf grammar.
