jailbreak quiz answers

break out of a counting loop by pressing button "A" #break #string #variables #docs

This is the answer key for the jailbreak quiz.

1. What does a 'break' statement do to a 'loop' ?

Exit a while or for loop before the loop is complete.

2. Consider the following directions

Write the line of code that will initialize a number variable to 0. Then create a second variable that tells us when we should break out of the loop. Set the break to false.

count = 0
shouldBreak = false

3. Consider the following directions

Write the line of code to stop incrementing count when the button is pressed. (Hint: This will set should break to true).

input.onButtonPressed(Button.A, () => {
    shouldBreak = true
})

4. Consider the following directions

Add an if statement to determine whether or not we should break out of the loop. Then include the message "I'm Out!" and a smiley face image displayed. This will happen right before you break from the while loop. **Do not include the break **

if (shouldBreak) {
    basic.showString("I'M OUT!", 150)
    images.createImage(`
. # . # .
. # . # .
. . . . .
# . . . #
. # # # .
`).showImage(0)
}
