1.3 What's with the Exercises?

Hands-on training gets the job done better. The best way to provide
this training is with a series of one or more exercises after every
half-hour to hour of presentation. Of course, if
you're a speed reader, the end of the chapter may
come a bit sooner than a half hour. Slow down. Take a breather. But
do the exercises.

Each exercise has a "minutes to
complete" rating. This rating hits the midpoint of
the bell curve but don't feel bad if you take
significantly longer or shorter. Sometimes it's just
a matter of how many times you've faced similar
programming tasks in your studies or jobs. Use the numbers merely as
a guideline.

Every exercise has its answer in Appendix A. Again, try not to
peek; you'll ruin the value of the exercise.
