Answer Key

Using a function call in OUTPUT
Section A: Quick Questions
Q1
B — OUTPUT SumSquare(10, 20)
Q2
A — The function runs and returns a value
Q3
A — OUTPUT "Sum of squares = ", SumSquare(10, 20)
Q4
B — OUTPUT SumSquare(10, 20)
Q5
A — Result = 8
Section B: Match the Pairs
Q1
OUTPUT SumSquare(10, 20) → Calls the function SumSquare with 10 and 20, then displays the value it returns
Q2
OUTPUT "Sum of squares = ", SumSquare(10, 20) → Displays the text first, then the value returned by the function call, on the same line
Q3
A function call can be placed straight into OUTPUT, so there is no need to store the result first → OUTPUT SumSquare(a, b)
Q4
A function result can be stored in a variable, and then the variable is displayed with OUTPUT → Total ← SumSquare(10, 20) OUTPUT Total
Q5
OUTPUT "Sum of squares = " SumSquare(10, 20) → There is no comma between the text and the function call, so the two items are not separated correctly
Q6
OUTPUT "Sum of squares = ", SumSquare → The function name is written without brackets and arguments, so the function is not called
Section C: Definitions
Q1
OUTPUT SumSquare(10, 20) — Puts a function call inside OUTPUT. The function runs first, then the value it RETURNs is displayed. Text can be added: OUTPUT "Sum = ", SumSquare(10, 20).
Section D: Fill in the Blanks
Q1
OUTPUT SumSquare(10, 20)
Q2
OUTPUT "Sum of squares = ", SumSquare(10, 20)
Q3
Total ← SumSquare(10, 20) OUTPUT "Sum of squares = ", Total
Q4
a ← 3 OUTPUT "Sum of squares = ", SumSquare(a, 4)
Q5
b ← 20 OUTPUT "Sum of squares = ", SumSquare(10, b)
Section E: Spot the Error
Q1
A — The function call is missing its closing bracket. It should be OUTPUT "Sum = ", Add(10, 20).
Q2
B — CALL is only used for procedures. A function is called by writing its name and arguments, so it should be Total ← SumSquare(10, 20).
Q3
D — A function call needs brackets, even when there are no parameters. Without them Ten is not called, so it should be Ten().
Q4
D — Quotes make Size a piece of text, so the word Size would be displayed. Without quotes, OUTPUT displays the value stored in the variable: OUTPUT "Area = ", Size.
Q5
C — The closing quote after the text is missing, so the function call becomes part of the string and is never run. It should be OUTPUT "Cube = ", Cube(N).
