Abstract

This chapter examines the various ways that data are made available to your programs. The concepts presented in this chapter are important because inadvertent access to a program’s data is a frequent source of program bugs. As a general rule, you want to restrict the access to a piece of data as much as possible. That way, inadvertent changes to the data are less likely, resulting in programs that have fewer bugs.
