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 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, and do the exercises!
Each exercise has a "minutes to complete" rating. We intend for this rating to hit 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 the Appendix. Again, try not to peek; you'll ruin the value of the exercise.
