Answer Key

INPUT

Section A: Quick Questions

A — INPUT Answer

A — INPUT Age

A — OUTPUT "Enter your name" INPUT Name

B — Each INPUT reads one value into one variable

B — INPUT Width INPUT Height

Section B: Match the Pairs

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

INPUT Scores[3] → Reads a value typed by the user and stores it in element 3 of the array Scores

Show a prompt with OUTPUT first, then read the user's reply into a variable → OUTPUT "Enter your age" INPUT Age

Use one variable per INPUT, so two values need two INPUT statements → INPUT Length INPUT Width

INPUT Length, Width → Two variables are listed in one INPUT. Each INPUT must read into only one variable.

INPUT "Enter a number" → A prompt in quotes is placed after INPUT instead of a variable name. INPUT needs a variable, and the prompt belongs in an OUTPUT statement.

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

INPUT Width
INPUT Height

FOR Index ← 1 TO 5
  INPUT Scores[Index]
NEXT Index

OUTPUT "Enter your name: "
INPUT Name

Section E: Spot the Error

B — Pseudocode uses the keyword INPUT to read a value typed by the user. READ is not a pseudocode keyword. It should be INPUT Name.

C — INPUT must name the variable that was declared. Aged is a different, undeclared variable, so the value would not be stored in Age. It should be INPUT Age.

A — The prompt is a string, so it must be written inside quotation marks. It should be OUTPUT "Enter your score".

C — Each INPUT reads into one variable only. Using INPUT A, B breaks the one-variable-per-INPUT rule. It should be INPUT A, with a separate INPUT B on the next line.

D — INPUT can only be followed by a variable name, not an expression. The calculation must be done after the value has been read. It should be INPUT Number.
