Unit 3 Lessons 1-9 (APCSP Code.org)

1. What does a “FOR LOOP” do? What is the variable, “I”, used for?

• a. FOR LOOP repeats a function for a set number of times; I is the number of times repeated

• b. I is a parameter of the function, and for only performs an action if certain circumstances are met

• c. The FOR LOOP is a function and I the absolute value of the function

• d. The FOR LOOP controls the order functions are called on outside of the for loop; I is the number of functions it controls

1. When is a good time to use a parameter?

• Choice A: When you need to repeat the same line of code multiple times without re-writing it each time

• Choice B: When you need to change the height, length, or size of something you are coding

• Both A and B

• Neither A nor B

moveForward() is an example of this:

• Parameter

• Function

• Conditional

• Library

This is a type of code that allows you to repeat a certain code over and over again without having to manually put it in.

• Function

• Parameter

• Loop

• API

What is an example of abstraction?

•  a. A loop to draw multiple birds
•  b. A function to draw a bird
•  c. moveForward (25) 
• d. arcLeft (90)

A collection of commands made available to a programmer:

• Algorithm

• Manual

• API

• AIG

In programming, an expression that evaluates to True or False. 

• Abstraction
• Boolean Expression
• Aggregate Expression
• None of the above

A description of the behavior of a command, function, library, API, etc.

• File
• Manual
• Documentation
• Formula

A particular kind of looping construct provided in many languages. Typically, it defines a counting variable that is checked and incremented on each iteration in order to loop a specific number of times.

• NOW LOOP

• IF LOOP

• FOR LOOP

• IF/NOW LOOP

A piece of code that you can easily call over and over again.

• Function
• File
• Folder
• Frame
