10: Name Control

Creating names is a fundamental activity in programming, and when a project gets large, the number of names can easily be overwhelming.

C++ allows you a great deal of control over the creation and visibility of names, where storage for those names is placed, and linkage for names.

The static keyword was overloaded in C before people knew what the term “overload” meant, and C++ has added yet another meaning. The underlying concept with all uses of static seems to be “something that holds its position” (like static electricity), whether that means a physical location in memory or visibility within a file.

In this chapter, you’ll learn how static controls storage and visibility, and an improved way to control access to names via C++’s namespace feature. You’ll also find out how to use functions that were written and compiled in C.
