Objective 2 Help

Inside the body of the loop, we're going to use the multiplier to get the multiple of 6. For example, if the multiplier is 1, then the multiple is 1 times 6, which is equal to 6.

Once you have a value, append it to the results array. This way once the for loop has iterated over the entire range, the array will contain the first 10 multiples of 6.

var results: [Int] = []

for multiplier in results { print("(1...10) time 6 is equal to (1...10 * 6)") }

THIS IS WHAT I WROTE FOR THE SECOND OBJECTIVE:

results.append(multiplier)

i don't really know what to write in there.

loops.swift 
// Enter your code below
var results: [Int] = []


for multiplier in results { 
     print("\(1...10) time 6 is equal to \(1...10 * 6)") 
     }

Hi Andrew Martinez! You're on the right track! I see you used append. But your for loop is set up as a range of for multiplier in results. First, this will never run. That's because results is an empty array. It wants us to fill up that array with... you guessed it... results!

// Enter your code below
var results: [Int] = []

for multiplier in 1...10 {
  results.append(multiplier * 6)
}

So here we start with the results array they give us. Now we're going to go through the range 1 to 10 as specified by the challenge. Every time through we're going to append the multiplier times 6. Our results array should end up looking like this: [6, 12, 18, 24, 30, 36, 42, 48, 54, 60]. I hope this helps! :sparkles:

They are looking for something like this: for multiplier in 1...10 { results.append(multiplier * 6) }
