Arrays
The area of computer memory that stores your pattern of dots is
called an array. Think of an array as an ordered set of cubby holes or
cells arranged in rows and columns (like Post Office boxes). Each cell
of the array corresponds to a dot position on the paper (Figure 15-2) .

Although the cells in a numeric array can hold any numeric con-
stant, we only need to concern ourselves with the two numbers one
and zero. Figure 15-3 demonstrates using a one to represent a dot and
a zero to represent no dot.
