- 2. Multiple Choice
In computer programming, this allows you to use a function knowing WHAT it does but not necessarily HOW it does it.

- 15. Multiple ChoiceA variable with local scope is one that can only be seen, used and updated by code within the same scope. Typically this means the variable was declared (created) inside a function -- includes function parameter variables.Local variableHome variableCommon variableGlobal variable
- 16. Multiple ChoiceDictates what portions of the code can "see" or use a variable, typically derived from where the variable was first created. (See Global v. Local)Variable ScopeVariable ViewVariable ProtocolVariable Interface
- 17. Multiple Choice
In the above picture, this would be an example of a:
Local Variable
Nested Variable
Global Variable
Variable Scope
- 18. Multiple Choice
In the above picture, this would be an example of a:
Local Variable
Nested Variable
Global Variable
Variable Scope
- 19. Multiple Choice
A variable whose scope is "global" to the program, it can be used and updated by any part of the code. Its global scope is typically derived from the variable being declared (created) outside of any function, object, or method.
Global Variable
Local Variable
Wide Variable
Limited Variable
- 20. Multiple Choice
A variable with local scope is one that can only be seen, used and updated by code within the same scope. Typically this means the variable was declared (created) inside a function -- includes function parameter variables.

- 21. Multiple Choice
A function must always have parameters in order for it to work.
True
False
- 22. Multiple Choice
A function must have a return value in order for it work properly.
True
False
- 23. Multiple Choice
A function can have a parameter(s) but not necessarily have a return value.
True
False
- 24. Multiple Choice
A function can have a return value but not necessarily have any parameters.
True
False
- 25. Multiple Choice
Which of the following is FALSE regarding functions?
(a) Functions with parameters and return values help us simplify our code
(b) A function can have parameters, but no return values
(c) A function can return multiple values at one time
A, B, C are all false
- 26. Multiple Choice
Look at this code. Which of the following will be shown in the console log when this program is ran?
This line always runs
This line always runs
But this one never does
But this one never does
Nothing will run in the console log
- 27. Multiple Choice
A function is also known as a procedure
True
False
- 28. Multiple Choice
An argument can include:
(a) a number
(b) a string
Both A and B
Neither A or B
- 29. Multiple Choice
Which of the following is FALSE regarding return values?
(A) It stops the flow of the function
(B) If a return is inside of a conditional, if that condition is met the function ends there.
(C) It returns a value to the place where the function was called.
None of these (A, B, C are all True)
- 30. Multiple Choice
A function return value can never be stored inside a variable.
True
False
- 31. Multiple Choice
In the example above, we say that lives is a local variable.
True
False
- 32. Multiple Choice
We say that function parameters are a form of a local variable because (choose all that apply):
they get created and initialized when a function is called
they get used while the function runs
they get destroyed when the function completes
they can be used both inside and outside of a given function
- 33. Multiple Choice
One of the disadvantages of writing functions that use parameters and return values is that it repeats code multiple times making your program disorganized and not very clean.
True
False
- 34. Multiple Choice
Once functions are written that take parameters and return values, it's easier to reuse that code in other places of your program.
True
False
- 35. Multiple Choice
Looking at this image, which of the following would be considered a parameter for the function totalCost?
total
check
cost
There are no parameters for this function
- 36. Multiple Choice
The function move(id, direction) could be used to move an element in any direction, rather than writing separate functions for each direction. This is considered an example of:
Modularity
Procedural Abstraction
Library
API
- 37. Multiple Choice

- 39. Multiple Choice
A library should have all of the following documentation EXCEPT:
(A) how each function works
(B) a complete list of the arguments
(C) what (if anything) will be returned
A, B, C should all be included
- 40. Multiple Choice
Looking at the above documentation here, what else should be included here (in place of the question marks)?
number
string
list
Can be either number, string, or list (depends)
- 41. Multiple Choice
Before adding a function to a library, check for any use of a local variables within the function. If there is, rework the function using global variables and a return.
True
False
- 42. Multiple Choice
Before adding a function to a library, check if another function is called in this function. If so, both functions should be included in the library.
True
False
- 43. Multiple Choice
When creating a library (check all that apply):
Same as functions; do not start with a Capital Letter
Same as a function; no spaces in the library name
"Library" must be included in the name
Include what type of value the return and/or parameter has (ex. string)
- 44. Multiple Choice
When we organize functions into a library and then call them in another program, we are really practicing this (check all that apply):
Modularity
API
Library
Procedural Abstraction
- 45. Multiple Choice
What are the benefits of using existing algorithms instead of brand new algorithms (check all that apply)?
reduced development time
reduced testing
simplification and identification of errors
