1. CheckPoint: Sequential and Selection Processing Control Structure

Read the following scenario:

You are an accountant setting up a payroll system for a small firm. Each line of the table in Appendix G indicates an employee’s salary range and corresponding base tax amount and tax percentage. Given a salary amount, the tax is calculated by adding the base tax for that salary range and the product of percentage of excess and the amount of salary over the minimum salary for that range.

Design a program that solves this problem.

Generate a set of input test values.

Perform a design walkthrough to verify your design.

1. CheckPoint: Iteration Control Structure

Design a program that models the worm’s behavior in the following scenario:

A worm is moving toward an apple. Each time it moves, the worm cuts the distance between itself and the apple by its own body length until the worm is close enough to enter the apple. The worm can enter the apple when it is within a body length of the apple.

IT 210 Week 8 CheckPoint Interfaces and Communications Messages

For more course tutorials visit

1. CheckPoint: Interfaces and Communication Messages

Understanding object-oriented methodologies is often difficult. You already understand that object-oriented analysis and design emulates the way human beings tend to think and conceptualize problems in the everyday world. With a little practice, object-oriented programming will become second nature to you.

As an example, consider a typical house in which there are several bedrooms, a kitchen, and a laundry room—each with a distinct function. You sleep in the bedroom, you wash clothes in the laundry room, and you cook in the kitchen. Each room encapsulates all the items needed to complete the necessary tasks.

You do not have an oven in the laundry room or a washing machine in the kitchen. However, when you do the laundry, you do not just add clothes to the washer and wait in the laundry room; once the machine has started, you may go into the kitchen and start cooking dinner. But how do you know when to go back to check the laundry? When the washer buzzer sounds, a message is sent to alert you to go back into the laundry room to put in a new load. While you are folding clothes in the laundry room, the oven timer may ring to inform you that the meat loaf is done.

What you have is a set of well-defined components: Each provides a single service to communicate with the other components using simple messages when something needs to be done. If you consider a kitchen, you see it is also composed of several, smaller components, including the oven, refrigerator, and microwave. Top-level objectsare composed of smaller components that do the actual work. This perspective is a very natural way of looking at our world, and one with which we are all familiar. We do the same thing in object-oriented programming:

o Identify components that perform a distinct service

o Encapsulate all the items in the component necessary to get the job done

o Identify the messages that need to be provided to the other components

Although the details can be quite complex, these details are the basic principles of object-oriented programming.

Consider the microwave oven in your kitchen, using the object-oriented thinking described above.

Create a table with the following four column headings: Top-Level Objects, Communicates With, Incoming Messages, and Outgoing Messages.

o Identity the top-level objects of the microwave.

o Explain some of the graphical user interfaces (GUIs) and communications messages that occur during the operation of a microwave.

Describe some of the advantages of having a componentized system. For example, what happens if the microwave breaks?
