Which of the following is FALSE regarding functions?

(c) A function can return multiple values at one time

(a) Functions with parameters and return values help us simplify our code

(b) A function can have parameters, but no return values

Look at this code. Which of the following will be shown in the console log when this program is ran?

This line always runs But this one never does

Nothing will run in the console log

Which of the following is FALSE regarding return values?

None of these (A, B, C are all True)

(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.

Look at this code. Which of the following will be shown in the console log when this program is ran?

Nothing will run in the console log

Which of the following is FALSE regarding guidelines you should follow in writing functions with return values?

(3) Return that variable outside of this function

(1) Decide what values you need as input to your computation. Make these parameters of your function.

(2) Use your parameters to calculate your result and save that result in a single variable.

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

Looking at this image, which of the following would be considered a parameter for the function totalCost ?

There are no parameters for this function

A library should have all of the following documentation EXCEPT:

(B) a complete list of the arguments

(C) what (if anything) will be returned

Looking at the above documentation here, what else should be included here (in place of the question marks)?

Can be either number, string, or list (depends)

In Lesson 7 you answered we discussed potential problems that could come up if you tried to use a function without knowing what it does or how to interact with it. Those included all of the following EXCEPT:

Determining what argument(s) your function needs

Guessing what value is returned

Finding an error when you run the code when the function is called

When creating a library (check all that apply):

Same as a function; no spaces in the library name

Include what type of value the return and/or parameter has (ex. string)

Same as functions; do not start with a Capital Letter

"Library" must be included in the name

As a user, what information would you need to know in order to use a particular library function?

You need to know the documentation for the functions so you can call them correctly and understand what will be returned

You need to know how the traversal looks in the function

You must know what arguments are used

You have to know what the coding looks like for the entire function

What are the benefits of using existing algorithms instead of brand new algorithms (check all that apply)?

simplification and identification of errors
