More information

The C Help Page in the CUED help system has links to many useful resources -

• Read the Frequently Asked Questions file if nothing else.
• The comp.lang.c newsgroup is informative. The ANSI C Rationale is a 100+ page DVI file justifying and describing ANSI C
• The Style Guide describes some useful conventions

• Look in just about any ftp archive for source code.
  The code at http://ftp.funet.fi/pub/languages/C/Publib has routines to manipulate sets, stacks, etc.
  In ftp://oak.oakland.edu/SimTel/msdos/c you'll find a big file of code snippets (currently version snip9510.zip) covering most subjects.
• The Lysator list of C resources is an excellent collection of documentary material.
