Answer Key

OUTPUT command

Section A: Quick Questions

A — OUTPUT "Welcome"

B — OUTPUT Score

A — OUTPUT "You have ", Lives, " lives left"

B — You have 3 lives left

A — OUTPUT can show text and variable values together

Section B: Match the Pairs

OUTPUT Score → Displays the current value stored in the variable Score on the screen

OUTPUT "You have ", Lives, " lives left" → Displays text, then the value of Lives, then more text, all in one command

OUTPUT can show a plain message to the user in quote marks → OUTPUT "Game over"

OUTPUT can be used as a user prompt to tell the user what to enter before an INPUT → OUTPUT "Enter your age: "

OUTPUT "You have " Lives " lives left" → The items are not separated by commas, so the command is invalid. Commas are needed between the text and the variable.

OUTPUT "Score" → The variable name is in quotes, so it displays the word Score instead of the value stored in the variable.

Section C: Definitions

OUTPUT — Displays text or values on screen. Text goes in quotes. Items are separated by commas, e.g. OUTPUT "You have ", Lives, " lives left". Also used for user prompts.

Section D: Fill in the Blanks

Score ← 50
OUTPUT Score

Lives ← 3
OUTPUT "You have ", Lives, " lives left"

OUTPUT "Enter your name: "
INPUT Name

Name ← "Sam"
Score ← 42
OUTPUT Name, " scored ", Score

Name ← "Sam"
OUTPUT "Hello ", Name, "!"

Section E: Spot the Error

C — Items in an OUTPUT command must be separated by commas. The comma is missing between "You have " and Lives. It should be OUTPUT "You have ", Lives.

B — Quotes make Score a piece of text, so this would display the word Score rather than 50. To display the value stored in the variable, write OUTPUT Score without quotes.

A — The text in the user prompt is missing its closing quote mark. It should be OUTPUT "Enter your name".

C — OUTPUT items are separated by commas, not semicolons. It should be OUTPUT "Cost: ", Price * Qty.

D — Putting Age in quotes outputs the word Age instead of the number the user entered. The variable must not be in quotes: OUTPUT "Age: ", Age.
