Question

(1 point)
• printing the names in a list until the user presses the space key
O printing all of the even numbers between 2 and 20
• telling a car to slow down if it is going over 40 mph
• printing a message if the user enters a negative number

Answer 1

The scenario that should use a for loop is:

• printing all of the even numbers between 2 and 20

A for loop is suitable here because you have a defined range of numbers (2 to 20) and you want to iterate through that range to select and print the even numbers in it. The other scenarios involve either waiting for an event (like a key press), checking a condition (like speed), or responding to user input (like a negative number), which are typically handled by while loops or event-driven programming.
