Plan plan plan plan plan and plan your code before writing it. Agree on interfaces between code bits ahead of time. C is a loose and rather permissive language so it is important to agree on coding standards. A CVS is a good idea. Document the code well. Maintain change logs. Document everything where reasonable. Abstract and encapsulate where reasonable. Modular code helps with group projects. It is one thing to be able to write code that you understand. It is another to write code that can be easily modified and understood by others.
