looper quiz answers
Learn how to create a series of numbers with a for loop.
This is the answer key for the looper quiz.
1. What is a for loop?
Answers will vary. In general, for loop refers to the code that repeats for a fixed number of times. We specify the LED using x, y coordinates.
2. Consider the following code
for (let i = 0; i < 4; i++) {
basic.showNumber(i, 150)
}
If the rectangle below represents the @boardname@, shade the areas that will be displayed. Explain why that particular area is shaded.
Let's create a for loop where 0 is the loop's starting value, i is the index variable, and 4 is the ending value. The index variable i starts at 0 and increases by 1 each time through the loop. The loop ends when i = 4.
3. Consider the following code
for (let i1 = 0; i1 < 6; i1++) {
basic.showNumber(i1, 150)
}
If the rectangle below represents the @boardname@, shade the areas that will be displayed. Explain why that particular area is shaded.
Let's create a for loop where 0 is the loop's starting value, i is the index variable, and 6 is the ending value. The index variable i starts at 0 and increases by 1 each time through the loop. The loop ends when i = 6.
