Answer Key

define: defining a function
Section A: Quick Questions
Q1
A — True
Q2
A — True
Q3
B — Yes
Q4
B — False
Q5
A — True
Section B: Match the Pairs
Q1
define addNumbers(a, b) → Starts a function named addNumbers with two parameters
Q2
end function → Closes a function definition
Q3
A keyword that starts a function's definition and names it → define
Q4
Values listed in brackets after the function name that the function accepts → (a, b)
Q5
DEFINE greetUser(name) DISPLAY "Hello " + name end function → The keyword should be written in lowercase as define, not DEFINE
Q6
define subtract(a, b) result ← a - b DISPLAY result func end → The closing keywords should be written as end function, not func end
Section C: Definitions
Q1
define — A keyword that starts a function definition, naming the function and listing the parameters it accepts
Section D: Fill in the Blanks

Q4
define multiply(x, y) result ← x * y DISPLAY result end function
Q5
define square(num) DISPLAY num * num end function
Section E: Spot the Error
Q1
D — A function definition must close with end function, not end func.
Q2
A — The keyword should be written in lowercase as define, not DEFINE.
Q3
B — Assignment in pseudocode uses ←, not =.
Q4
