append results of for in loop to array

var results: [Int] = []

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

so this is the code, and for test 2 I should take the results of the for in loop and append the results variable. I know how to append variables. but I don't know how to append all the results of that loop to the variable. I don't think the video ever discussed how to append all the results of another line of the code, anyways thats besides the matter. Thanks for any help!!!

For the above to work the way you want you will need to use:

print("(multiplier) times 6 is equal to (multiplier * 6)")

Or you will get the word instead of the variable. Int's inside of quotes need the back slash.

On step 2 if you add some thing like:

results.append( multiplier * 6 )

You will then call the append method on results and put the times 6 value on the end array.

As an added critique I think you will need to use:

let multiplier: Int

Before that For in Loop

Hey! You're on the right track with your for loop, but instead of printing, they are looking for you to implement some of the concepts taught in earlier courses.

You've mentioned that you know how to append, so for this situation, you would replace your 'print' statement with your 'append' statement - your loop should look something like this: 

for multiplier in 1...10 {
    results.append( /*insert whatever you want to append here */)
}

Hope that helps!
