Algorithm Header and Structure

The required header keyword that names a VCAA maths pseudocode algorithm. Written as Algorithm: followed by a descriptive name, it must appear as the first line before input or processing

Part of: VCE Pseudo Code — Module 6, QCE Digital Solutions Unit 1 — Algorithms and Programming Techniques — Module 12

Understanding Algorithm Header and Structure in VCE Pseudocode

What it does: The first line Algorithm: compute average shows the correct form — capital A, colon, and a descriptive name that explains what the algorithm does. Begin and End mark the boundaries of the SD pseudocode algorithm body. The statements inside are indented to show they belong within the block. The algorithm structure is: Algorithm header first, then input to collect values, then processing, then print to display results.

Common mistakes: The keyword algorithm must have a capital A in VCAA pseudocode. The correct header is Algorithm: find maximum. Line 0 is wrong. The Algorithm header requires a colon after the keyword: Algorithm: find the sum. Without the colon the header does not follow VCAA convention. Line 0 is wrong.

Quick Questions

1. Which is the correct first line of a VCAA maths pseudocode algorithm?

A. Algorithm: find the total ✓

B. algorithm: find the total

The keyword Algorithm must have a capital A. Lowercase `algorithm` does not follow VCAA pseudocode convention.

2. What punctuation mark must follow the word Algorithm in a VCAA maths pseudocode header?

A. A dash — Algorithm - name

B. A colon — Algorithm: name ✓

The VCAA pseudocode algorithm header always uses a colon directly after the keyword: `Algorithm: descriptive name`.

3. In a VCAA maths pseudocode algorithm, where does the input statement appear?

A. After the processing and print statements

B. After the Algorithm header, before processing ✓

The algorithm structure is: Algorithm header first, then input to collect values, then processing, then print to display results.

4. Which keywords wrap the body of a VCE Software Development pseudocode algorithm?

A. Begin ... End ✓

B. Start ... Finish

VCE Software Development pseudocode uses `Begin` to open the algorithm body and `End` to close it. `Start` and `Finish` are not valid VCAA keywords.

5. Can a VCAA maths pseudocode algorithm have a second Algorithm: header inside its body?

A. No — each algorithm is a separate independent unit ✓

B. Yes — nested Algorithm headers are allowed

Each algorithm is a self-contained named unit. A second Algorithm header cannot appear inside the body of an existing algorithm.

Match the Pairs

Algorithm: find the larger input a, b if a > b then print a → A complete VCAA maths pseudocode algorithm: Algorithm header names it, input collects values, then processing and output follow in order

Begin result <- a + b Print result End → A complete VCE Software Development pseudocode algorithm: Begin opens the body, statements are indented inside, and End closes it

The Algorithm: header must be the first line of a VCAA maths pseudocode algorithm and uses a capital A and a colon → Algorithm: compute average input x, y average <- (x + y) / 2 print average

In VCE Software Development pseudocode, Begin opens and End closes the algorithm body; all statements inside are indented → Begin score <- x * 10 Print score End

algorithm: find total input a, b total <- a + b → Wrong — the keyword must have a capital A: `Algorithm: find total`. Lowercase `algorithm` does not follow VCAA convention

Algorithm find the sum input a, b print a + b → Wrong — the Algorithm header requires a colon: `Algorithm: find the sum`. Without the colon the header does not follow VCAA pseudocode convention

Fill in the Blanks

1. Algorithm: calculate area input l, w area <- l * w

Hint: Type the required first keyword that begins every named VCAA maths pseudocode algorithm

2. Algorithm: find the total input a, b total <- a + b

Hint: Type the first word of the descriptive name that explains what this algorithm does

3. Algorithm: check age input age if age >= 18 then

Hint: Type the keyword that accepts the user's value before processing begins

4. Begin total <- a + b Print total End

Hint: Type the keyword that opens the body of a VCE Software Development pseudocode algorithm

5. Begin result <- x * 2 Print result End

Hint: Type the keyword that closes the body of a VCE Software Development pseudocode algorithm

Spot the Error

Question 1

A algorithm: find maximum

B input a, b

C print a

Line A — The keyword `algorithm` must have a capital A in VCAA pseudocode. The correct header is `Algorithm: find maximum`. Line 0 is wrong.

Question 2

A Algorithm find the sum

B input a, b

C total <- a + b

D print total

Line A — The Algorithm header requires a colon after the keyword: `Algorithm: find the sum`. Without the colon the header does not follow VCAA convention. Line 0 is wrong.

Question 3

A Algorithm: compute product

B product <- p * q

C input p, q

D print product

Line B — `product <- p * q` appears before `input p, q`. The variables p and q have not been given values yet. Input must come before any processing that uses those variables. Line 1 is wrong.

Question 4

A Algorithm: show double

B input n

C result <- n * 2

D print result

E Algorithm: check value

Line E — A second Algorithm header cannot appear inside the body of an existing algorithm. Each named algorithm is a separate independent unit. Line 4 is wrong.

Question 5

A Begin

B area <- l * w

C Print area

D Finish

Line D — In VCE Software Development pseudocode, the closing keyword is `End`, not `Finish`. The body opened with `Begin` must be closed with `End`. Line 3 is wrong.
