Quick Questions

Shade in the A or B circle for each question.

1. Which is the correct VCAA maths pseudocode statement to output a result?

A print area

B display area

2. Where in a VCAA pseudocode algorithm should print statements appear?

A Before input — to show what the user should enter

B After processing — to display the final result

3. Which style of pseudocode uses Print with a capital P?

A VCE Software Development Begin...End pseudocode

B VCE Maths pseudocode

4. Can print output a computed expression directly?

A No — print can only output stored variables

B Yes — for example: print total / count

5. Which correctly outputs a result in VCAA maths pseudocode?

A print result

B PRINT result

Match the Pairs

Draw a line connecting each item on the left to its match on the right.

Left column		Right column
1print area		AAlgorithm: find area input l, w area <- l * w print area
2print total / count		BWrong — print must come after input and processing. Printing result before n has been entered and result has been calculated produces no meaningful output
3print outputs the result after all input and processing has been completed		CEvaluates the expression total divided by count and outputs the computed result directly without storing it in a variable
4Capital-P Print is used in Software Development Begin...End pseudocode, not in VCAA maths pseudocode		DOutputs the current value stored in the variable area to display it as the result of the algorithm
5display answer		EBegin result <- a + b Print result End
6print result input n result <- n * 2		FWrong — `display` is not a VCAA pseudocode keyword. The correct output keyword is `print`. The line should read `print answer`

Answer Key

print keyword

Section A: Quick Questions

A — print area

B — After processing — to display the final result

A — VCE Software Development Begin...End pseudocode

B — Yes — for example: print total / count

A — print result

Section B: Match the Pairs

print area → Outputs the current value stored in the variable area to display it as the result of the algorithm

print total / count → Evaluates the expression total divided by count and outputs the computed result directly without storing it in a variable

print outputs the result after all input and processing has been completed → Algorithm: find area input l, w area <- l * w print area

Capital-P Print is used in Software Development Begin...End pseudocode, not in VCAA maths pseudocode → Begin result <- a + b Print result End

display answer → Wrong — `display` is not a VCAA pseudocode keyword. The correct output keyword is `print`. The line should read `print answer`

print result input n result <- n * 2 → Wrong — print must come after input and processing. Printing result before n has been entered and result has been calculated produces no meaningful output

Section C: Definitions

print — A VCAA pseudocode keyword that outputs a value, variable or expression as a result. Example: print area displays the current value stored in the variable area

Section D: Fill in the Blanks

print area

Algorithm: show total
input a, b
total <- a + b
print total

input x
result <- x * 2
print result

average <- total / count
print average

Begin
  result <- a + b
  Print result
End

Section E: Spot the Error

C — `display n` is not valid VCAA pseudocode. The correct keyword for outputting a value is `print`. The line should read `print n`. Line 2 is wrong.

C — `print a + b <- total` incorrectly mixes print with an assignment. print only outputs a value — it cannot assign. The assignment `total <- a + b` and the output `print total` must be on separate lines. Line 2 is wrong.

B — `print result` appears before result has been given a value. print must come after input and processing, not before them. Line 1 is wrong.

D — `PRINT square` uses all capitals, which is not standard VCAA maths pseudocode. The correct form is `print square` in lowercase. Capital-P `Print` is used in SD Begin...End style, not PRINT in all capitals. Line 3 is wrong.

E — `input z` appears after `print average`, which is out of order. All input statements should appear before processing and output. An input after the final print statement has no purpose in this algorithm. Line 4 is wrong.
