how to add these?

hi guys! thanks so much for helping!

my code is working on my Xcode so I have found the right values, I am pretty sure the logic is fine on these. But I can't find a way to correctly append these values to my results array, please help.

logicalOperators.swift
var results: [Int] = []

for n in 1...100 {
    // Enter your code below
   if n % 2 == 0 && n % 7 == 0 {
   print (n)
   } 

    // End code 
}

Hey Valeria,

You're on the right track, but there are a few of things.

  1. First, the challenge wants you to check that the number is odd. You are using n % 2 == 0 which is seeing if it is even, so you need to change the == to !=, so it checks that it is NOT even.

  2. The challenge did not ask you to print out the values (and the challenge is picky), so you need to delete that line.

  3. To append to the array, you use dot notation and append the value.

Final code will be:

var results: [Int] = []

for n in 1...100 {
    // Enter your code below
   if n % 2 != 0 && n % 7 == 0 {
    results.append(n)
   } 
}

Hopefully this makes sense. Any other questions, please comment back. :dizzy:
