detailed question

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.

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 = value % divisor

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

1 Answer

The task 1 expression is absolutely correct. The mistake is in task 2.

The equality operator(==) checks whether the result of two expressions comes out to be equal or not and hence returns true or false. The assignment operator(=) on the other hand assigns a value to a constant or variable. The problem with the code is that you are assigning 0 to the result constant instead of checking it using the equality operator as asked in the question. Hope this helps :)

// 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 = value % divisor

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