iOS Swift Basics Swift Operators Working With Operators

Help!! Completely confused by this!

In the editor below, you have two constants - value and divisor. Step 1: Using the remainder operator, compute the remainder given the value and a divisor. Assign this value to a constant named result.

Step 2: When value obtained using a remainder operator is 0, this means that the value is a perfect multiple of the divisor. Compare the value of result to 0 using the equality operator and assign the resulting value to a constant named isPerfectMultiple.

// Enter your code below
let value = 200
let divisor = 5

let someOperation = 20 + 400 % 10 / 2 - 15
let anotherOperation = 52 * 27 % 200 / 2 + 5

// Task 1 - Enter your code below

// Task 2 - Enter your code below

Hi Brianna

The first step is asking you to compare value and divisor, provided for you, with the mod operator, %. Store the result of that into a constant named result.

That looks like:

// Task 1 - Enter your code below
let result = value % divisor

Next, you want to see if result equals zero. So, compare result to zero using the double-equals operator, ==. Store the result of that comparison in a constant named isPerfectMultiple. That looks like:

// Task 2 - Enter your code below
let isPerfectMultiple = result == 0

So, you assign, with a single equals, the result of comparing result to zero using double-equals. The comparison will result in a true or false answer, so isPerfectMultiple will contain one of those two values.

I hope that helps.


No problem! :+1: :smile:
