Programs to Complete
Much of the work of a programmer is developing and maintaining existing systems. This section contains incomplete programs for you to examine, test, and then complete in different ways. We are grateful to Adam Renak for allowing us to adapt his code to provide you with program BookCollection and program Cards. If you have any incomplete programs that could be usefully recycled in this way, we would be pleased to receive them from your school. Although the student programs in the main section work without any changes, you may have ideas on how to develop them. We hope that your school will return some completed and developed programs to include on the site, so that we will be able to model the industrial process for developing free and open source software.
