Natalie wants the player to be able to make the cat move and complete in 10 moves with key presses. Which programming component is needed to tell the program it must do something when a specific key is pressed?

• A. An event for each key
• B. A condition
• C. A loop
• D. A function that runs on startup

Answer: (A)

Handling user input is best dealt with through events. To make the cat move exactly when the player presses a key, you attach an event for that key that runs a specific piece of code whenever the key press occurs. This event-driven setup links the user action directly to the behavior, so each press causes a move and helps tally the 10 moves you want. Using a condition would require constantly checking the key state, which can miss or mis-handle single presses. A loop would keep running and might cause continuous movement rather than a discrete response to each press. A function that runs on startup executes only once, at the beginning, and won’t respond to key presses after that. So an event for each key is the right approach to trigger actions precisely when the key is pressed.
