Explain a sequence structure in programming; give an example.
It is the order of operations for a method; steps from beginning to end without deviation

Explain what a decision structure is. Give an example.
A conditional statement; the use of If/Else drives what actions the programs should take.
200
How do you cause multiple things to happen if a condition is true?
Create multiple outcomes listed under the If statement
200
What are the three basic flowchart symbols and what does each represent?
oblong, diamond, rectangle
200
What are logical operators and when are they used?
test whether conditions are true or false

What is the largest state in America, in terms of land mass?
Alaska, with 571,951 square miles (more than twice the size of Texas!)...ironically, it has the lowest population density per square mile

Explain Boolean variables and their possible outcomes. Surprise! Use an example.
Only two values-true or false.
300
What is a nested If/Else statement?
An If/Else as a potential outcome for an If statement

Why are you looking here? You should know this stuff!

Assume that a = 1, b = 2, and c = 3. What is the value of the expression: both a < b and b > c?
false
400
What are the three common logical operators used in programming?
not a; both a and b; either a or b, or both
400
What is the largest state in terms of population?
California, with 38,000,000 (and #2 is Texas...hmmm...)
500
Explain the difference between a structure and a function, which can only be accomplished using examples!
That's also way too long to type
500
What are the outcomes of a Boolean operator? How are these expressed in flowcharting and in a decision structure?
True/False, as the two outcomes of a diamond, as the If and the Else outcomes
500
How do you create a decision structure that causes an object to take an action based on a property? And, what are some properties that can be used in such a statement? What does the latter depend on?
select the object, click properties tab, drag the tile into the If/Else, pick something to compare. color, opacity, brightness; depends on the object
500
Explain how the 'not a' operator works and yes...you need an example
I'm sure you got it right!
