Answer Key

Input with INPUT

Section A: Quick Questions

A — INPUT Age

A — DECLARE Age : INTEGER INPUT Age

B — Into the variable Answer

A — 42

B — OUTPUT "Enter your name" INPUT Name

Section B: Match the Pairs

INPUT Age → Waits for the user to type a value and stores it in the variable Age

OUTPUT "Enter your name: " → Shows a prompt so the user knows what to type before the INPUT statement

The variable must be declared before it is used to store the input → DECLARE Score : INTEGER INPUT Score

Ask the user with OUTPUT first, then read their answer with INPUT → OUTPUT "Enter a number: " INPUT Number

INPUT "Age" → INPUT needs a variable name (identifier), not a string in quotes. It should be INPUT Age.

DECLARE Age : INTEGER INPUT Age // user types: hello → Age is an INTEGER, so the user cannot enter text like hello. The type decides what can be entered.

Section C: Definitions

INPUT Answer — Reads a value typed by the user and stores it in the variable named after INPUT (here Answer). Declare the variable first; its data type decides what can be entered.

Section D: Fill in the Blanks

DECLARE Age : INTEGER
OUTPUT "Enter your age: "
INPUT Age

DECLARE Name : STRING
OUTPUT "Enter your name: "
INPUT Name

DECLARE Score : INTEGER
OUTPUT "Enter your score: "
INPUT Score

DECLARE Price : REAL
OUTPUT "Enter the price: "
INPUT Price

DECLARE Colour : STRING
OUTPUT "Favourite colour? "
INPUT Colour

Section E: Spot the Error

C — Cambridge pseudocode uses the keyword INPUT to read a value from the user, not READ. The line should be INPUT Name.

C — INPUT is a statement, not a value to assign. The variable name goes after INPUT, so the line should be INPUT Age.

B — Mark was never declared. INPUT must name a declared variable, so the line should be INPUT Score.

B — INPUT needs a variable identifier, not a string in quotes. There should be no quotes: INPUT Price.

D — Several values in one OUTPUT must be separated by commas. The comma is missing after the text: OUTPUT "You chose ", Count.
