iOS Swift 2.0 Basics Swift Operators Working With Operators

Swift 2.0 I'm stuck, I need help

Challenge Task 1 of 2

For the first task, we're going to keep it pretty simple and check if we know how to use the reminder and equality operators.

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.

Submit your answer after you've completed both steps 1 and 2. I'm stuck, I need help

operators.swift
// 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
let result = 40 
// Task 2 - Enter your code below

let isPerfectMultiple = 0

Hey Ary,

The first step of this challenge is to use the remainder operator (%). Here's how you use it:

let result = value % divisor

The second part is to use the equality operator (==) to test if the result equals to 0. If result equals to 0, isPerfectMultiple will equal to True. Otherwise isPerfectMultiple will be equal to False.

let isPerfectMultiple = (result == 0)

Good luck! :)

Thank you Richard i will try it today . cool... Ary

I used this, is that cool? It passed...

let result = value % divisor

let isPerfectMultiple = result == 0

For the first step of the challenge I have two questions;

  1. Why did you use the (%) symbol for this answer?

  2. How did you know to use the (%) symbol for this answer?

Thank you for your response in advance

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
let result = value % divisor
// Task 2 - Enter your code below
let isPerfectMultiple = (result == 0)

let result = value % divisor

let isPerfectMultiple = (result == 0)

// 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

value % divisor

// Task 2 - Enter your code below

let isPerfectMultiple = value % divisor == 0
