2. Output Programs These slides will present a variety of small programs. Each program has a control structure that was introduced in this chapter. Our concern will be with the output of each program, and more importantly, to develop a way to determine program output correctly for programs that involve control structures. You can expect that on quizzes and/or tests only a program segment or a method is shown.

3. Teacher/Student Versions, Tablet PCs, and Inking The “For Teachers” version of this presentation has 2 slides for each program. The first slide only shows the program. The second shows the program, worked out solution, and output. The “For Students” version only has 1 slide for each program with no provided solution or output. Students are expected to work out the solutions either on paper, or ideally they can “ink” directly on their laptops.
