If statements

How do you write an if statement inside the loop to carry out the desired checks and if the number is indeed both an odd number and a multiple of 7, append the value to the results array provided ?

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

for n in 1...100 {
    // Enter your code below


    // End code 
}

Number is odd when divided by 2 leaves some reminder - n % 2 != 0 Number is a multiple of 7 when divided by 7 leaves no reminder - n % 7 == 0 so the 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)
    }
    // End code
}

let isOdd = n % 2 != 0 // if the remainder of two is not zero then it is an odd number
let dividableBySeven = n % 7 == 0 // if the remainder of seven is equal to zero, then the number is dividable by seven
if isOdd && dividableBySeven {
    results.append(n)
}
