IT 210 Week 8 Check Point 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 objects are 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:
Identify components that perform a distinct service
Encapsulate all the items in the component necessary to get the job done
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 columns and use the following headings: Top-Level Objects, Communicates With, Incoming Messages, and Outgoing Messages.
Create rows in the table to fill in the columns for each of the Top-Level Objects found on a microwave.
Also in the table 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 microave breaks?

IT 210 Week 4 Check Point Repetition Control Structure
Read the following scenario:
In one of the week 3 discussion questions we discussed the algorithm that would be required to make a peanut butter sandwich.
In this CheckPoint you will need to take that one step further and create a program design to make a peanut butter sandwiches. In Appendix H in the Course Materials forum you will find a partial program design; you need to complete it by adding the pseudocode in the required areas. You need to add one repetition (loop) control structure and one decision control to complete the program design. The user will decide how many sandwiches are made; this is where the loop will be used. The user will decide if the sandwich includes jelly, and, if it does, what flavor of jelly; to keep it simple we are only allowing grape or strawberry jelly.
Design a program with pseudocode that solves this problem.
Your solution should look like the example provided in Appendix E in the Course Materials forum; it must include the program analysis (process, input, and output) and the pseudocode.
