Chapter 18, Problem 12QY

To properly define a variable, you must also provide its "type" and "other properties," in addition to the variable's name. All variables, in other words, contain more information about them than just their data type. In the future, we will be able to better describe the qualities of any variable if you could please elucidate on the idea that would make this possible.

What will the designer's first assignment be?

How may the Designer's bounding box tell you something useful about an object's characteristics?

In the same way that attributes dictate whether or not a control is shown on the form at runtime, attributes also determine whether or not a control is displayed on the form at design time.

I've posted this question once before but was a little confused by the answer. I was wondering if you could please also draw the design in Logisim and post that as a part of the answer. That would make it more clear for me to understand.

To declare a variable, "type" alone is not enough. Every variable is distinguished by its data type and a set of additional characteristics. So how can we make use of this idea, which allows us to describe any variable's properties?

When and how should you use a checklist during testing? Similarly to selecting a relevant real-life illustration for your assignment.

How may the Designer's bounding box provide useful information about an object's characteristics?

the description looks similar, what are the differences then?
