This same structure serves as the framework for the discussion
questions and exercises at the end of each chapter in this topic. The
question numbers provide the main context and guidance for a
problem, and sometimes this information is adequate to designate
an entire problem; however, some questions involve several related
subquestions, and these are designated a, b, c.
In the terminology of computing, this general approach to prob
lem solving is called a
top-down methodology
. Think of the entire
problem as being at a top level, and subproblems make up lower
level details. (Because an outline form uses indenting to show the
