Working with Logical Operators

Could someone explain this challenge?

logicalOperators.swift 
var results: [Int] = []
var even = 0
var odd = 1
for n in 1...100 {
    // Enter your code below
    if 100 % 1 = 0 {
    print("Even")
    } else { 
        print("Odd")
    // End code 
}

Hi Fahiye,

I think you'll actually want to use 

n % 2 = 0

The reason is that the modulo operator is being used here to determine if any given number is even, which means it's divisible by 2. (hence, n % 2 = 0). Since all numbers are divisible by 1, 100 % 1 (or n % 1) will always result in true statement - your loop will never reach the else clause.

Hope that helps! Cena
