Answer Key

Layout conventions for Cambridge pseudocode

Section A: Quick Questions

B — DECLARE TotalScore : INTEGER

A — OUTPUT "Hello"

B — PlayerName

A — Four spaces

A — CONSTANT MaxScore ← 100

Section B: Match the Pairs

DECLARE TotalScore : INTEGER → A keyword in upper case followed by an identifier in PascalCase, the standard layout for declaring a variable

<identifier> → A meta-variable in angled brackets that stands for any identifier you choose to write

Keywords such as CONSTANT are written in upper case and identifiers use PascalCase → CONSTANT MaxScore ← 100

Lines inside a statement are indented by four spaces → IF Score > 50 THEN OUTPUT "Pass" ENDIF

declare totalscore : integer → The keywords DECLARE and INTEGER are written in lower case. They must be in upper case, and the identifier should be PascalCase: DECLARE TotalScore : INTEGER

IF Age >= 16 THEN OUTPUT "Adult" ENDIF → The lines inside the IF statement are not indented. THEN and OUTPUT should be indented by four spaces.

Section C: Definitions

DECLARE TotalScore : INTEGER — Pseudocode layout convention: keywords in UPPER CASE, identifiers in PascalCase, and lines inside a statement indented four spaces. Meta-variables use angled brackets, like <identifier>.

Section D: Fill in the Blanks

DECLARE TotalScore : INTEGER

CONSTANT MaxScore ← 100

INPUT PlayerName

IF Score > 50 THEN
    OUTPUT "Pass"
ENDIF

DECLARE <identifier> : <data type>

Section E: Spot the Error

A — Keywords such as DECLARE are always written in UPPER CASE. The line should be DECLARE Score : INTEGER.

B — INPUT is a keyword, so it must be in UPPER CASE. The line should be INPUT Name.

D — NEXT is a keyword, so it must be written fully in UPPER CASE, not mixed case. The line should be NEXT Count.

B — Cambridge identifiers use PascalCase, with no underscores or lower-case first letter. It should be DECLARE TotalScore : INTEGER.

C — Meta-variables in Cambridge pseudocode are written in angled brackets <like this>, not square brackets. It should be INPUT <identifier>.
