Consider the situation where you are making a presentation on the computer programming process. You have a slide with the following text:
Solving a problem on a computer involves the following activities
(1) Define the problem.
(2) Analyze the problem.
(3) Develop an algorithm for solving the problem.
(4) Write the computer program which implements the algorithm.
(5) Test and debug the program.
(6) Document the program.
(7) Maintain the program.
However, you don’t want all seven items to appear immediately. You want them to appear one at a time, after you have finished discussing the previous one. So, when the slide comes up, the only thing you want to see is
Solving a problem on a computer involves the following activities
Then, when you click the mouse, the first activity should appear. Your slide should look like this:
Solving a problem on a computer involves the following activities
(1) Define the problem.
After you’ve discussed the first point, you want to click and have the second activity appear, thus:
Solving a problem on a computer involves the following activities
(1) Define the problem.
(2) Analyze the problem.
After discussing the second activity, you click and the third appears. This process continues until all the activities are discussed.
