Answer Key

INPUT command

Section A: Quick Questions

B — INPUT Age

A — Reads what the user types and stores it in Answer

A — OUTPUT "Enter your name" INPUT Name

A — INPUT Height

B — INPUT

Section B: Match the Pairs

INPUT Answer → Reads a value typed by the user and stores it in the variable Answer

OUTPUT "Enter your age" → Shows a prompt message so the user knows what to type before the INPUT

Show a prompt first, then read the user's value into a variable → OUTPUT "Enter your name" INPUT Name

Use one variable per INPUT to read two separate values → INPUT Length INPUT Width

INPUT Length, Width → Two variables are listed in one INPUT. Each INPUT must read into only one variable, so use INPUT Length then INPUT Width on separate lines.

INPUT "Enter your age" → INPUT needs a variable name, not a prompt string. Use OUTPUT for the prompt and then INPUT Age to store the value.

Section C: Definitions

INPUT Answer — INPUT followed by a variable name reads a value typed by the user and stores it in that variable. Use one variable per INPUT, and OUTPUT a prompt first.

Section D: Fill in the Blanks

INPUT Answer

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

OUTPUT "Enter your name"
INPUT Name

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

OUTPUT "Enter a number"
INPUT Number
OUTPUT Number * 2

Section E: Spot the Error

A — INPUT reads a value into a variable, so it needs a variable name, not a message. Use OUTPUT to show the prompt: OUTPUT "Enter your name".

C — Cambridge pseudocode keywords are written in capital letters. It should be INPUT Score.

A — A DECLARE needs a colon between the variable name and its data type. It should be DECLARE Height : REAL.

C — INPUT is a command followed by the variable name. It is not a value you assign with ←. It should be INPUT Mark.

D — Use one variable per INPUT. Name was already read on line 2, so line 4 should be INPUT Age.
