Understanding Pseudocode Writing Conventions in VCE Pseudocode

What it does: Each assignment and print statement appears on its own line, following the one-statement-per-line convention. print i is indented to show it is inside the for loop body. end for is not indented because it closes the block at the outer level. VCAA pseudocode always writes the closing keyword as two words: end followed by a space and then the matching block keyword. VCAA pseudocode does not use semicolons. A statement simply ends when the line ends. This snippet demonstrates all three core writing conventions: one statement per line, indentation to show nesting, and end if as the required closing keyword.

Common mistakes: The body of an if block must be indented to show it is inside the block. Line 1 should be print score with leading spaces. Line 1 is wrong. VCAA pseudocode requires one statement per line. x <- 5 and print x must each appear on their own separate line. Semicolons are not used in VCAA pseudocode. Line 0 is wrong.

Quick Questions

1. Which is the correct VCAA way to close an if block?
A. end if ✓
B. endif
VCAA pseudocode always writes the closing keyword as two words: `end` followed by a space and then the matching block keyword.
2. How many statements should appear on one line in VCAA pseudocode?
A. One statement per line ✓
B. Multiple statements are fine
One statement per line is a core VCAA convention. It keeps pseudocode readable and unambiguous.
3. What does indentation show in VCAA pseudocode?
A. Nothing — it is just a style preference
B. That lines belong inside a nested block ✓
Indentation is a mandatory VCAA convention that visually shows which lines are inside a loop, if block or function body.
4. Which correctly closes a for loop in VCAA pseudocode?
A. end loop
B. end for ✓
Each block is closed with `end` followed by the same keyword that opened it. A for loop opens with `for`, so it closes with `end for`.
5. Does VCAA pseudocode use semicolons to end statements?
A. No — statements end at the end of the line ✓
B. Yes — semicolons are required
VCAA pseudocode does not use semicolons. A statement simply ends when the line ends.

Match the Pairs

end if → The closing keyword for an if block in VCAA pseudocode; end is always followed by a space and the keyword that opened the block
if temp > 30 then print "hot" else print "cold" end if → A snippet showing all three VCAA conventions: one statement per line, the body indented inside each block, and end if closing the construct
One statement per line is a core VCAA pseudocode writing convention → x <- 5 y <- x + 1 print y
Indentation shows which lines belong inside a nested block such as a loop or if statement → for i from 1 to 5 print i end for
if age > 18 then print "ok" endif → Wrong — VCAA pseudocode writes this as two words: `end if`. The closing keyword always separates end from the block name with a space
x <- 5; print x if x > 0 then print "ok" end if → Wrong — VCAA pseudocode requires one statement per line. Semicolons are not used. `x <- 5` and `print x` must each be on their own line

Key Term

end if
A closing keyword in VCAA pseudocode that ends an if block; every nested construct uses end followed by its matching keyword: end if, end while, end for

Fill in the Blanks

1. if score > 50 then print score end if
Hint: Type the keyword that begins every closing statement in VCAA pseudocode
2. while count < 10 print count end while
Hint: Type the keyword that matches the loop type being closed
3. for i from 1 to 5 print i end for
Hint: Type the keyword that identifies which kind of loop is being closed
4. if x > 5 then print x end if
Hint: Type the keyword that opens the body of an if block in VCAA pseudocode
5. if a > b then print a end if
Hint: Type the keyword that names the block being closed — it must match the keyword that opened this block

Spot the Error

Question 1
A if score > 50 then
B print score
C end if
Line B — The body of an if block must be indented to show it is inside the block. Line 1 should be ` print score` with leading spaces. Line 1 is wrong.
Question 2
A x <- 5; print x
B if x > 0 then
C print "positive"
D end if
Line A — VCAA pseudocode requires one statement per line. `x <- 5` and `print x` must each appear on their own separate line. Semicolons are not used in VCAA pseudocode. Line 0 is wrong.
Question 3
A if age >= 18 then
B print "Adult"
C endif
Line C — The closing keyword must be written as two words: `end if`, not `endif`. VCAA pseudocode always separates end from the block keyword with a space. Line 2 is wrong.
Question 4
A if x > 5:
B print x
C end if
Line A — VCAA pseudocode uses `if condition then`, not a colon. Colons are Python syntax and have no place in VCAA pseudocode. The correct line is `if x > 5 then`. Line 0 is wrong.
Question 5
A while count < 10
B print count
C count <- count + 1
D endwhile
Line D — The closing keyword for a while loop must be written as two words: `end while`, not `endwhile`. VCAA pseudocode always separates end from the block keyword with a space. Line 3 is wrong.
