Most programming time is spent modifying and debugging existing code. Software does not exist in a vacuum; it must be documented, maintained, enhanced, and sold. In this chapter we take a look at a small programming project using one programmer. Larger projects that involve many people are discussed in Chapter 23 . Although the final code is fewer than a hundred lines, the principles used in its construction can be applied to programs with thousands of lines of code. Figure 7-1 illustrates the software life cycle.
