A-2. Legend for code skeletons
This book includes many code skeletons that provide a schematic bird’s-eye view of the code. You can find the first code skeleton in chapter II-1. The legend for all the code skeletons is shown in Figure 1 below.
In some skeletons, we use dashed rectangles to highlight certain parts of the code. In those cases:
- A green dashed rectangle indicates that the code has been added. See Figure 2 in chapter II-4.
- A red dashed rectangle indicates that the code has been removed. See Figure 3 in chapter II-4.
- A blue dashed rectangle indicates that the code has been modified. See Figure 4 in chapter II-4.
