How do I get the results from my for in loop to display in the results variable without doing it manually?

//How do I get the results from this

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

//To display in this

var results: [Int] = []

I was able to do it manually like this

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

var results: [Int] = [6,12,18,24,30,36,42,48,54,60]

But I had to enter the numbers manually, and I feel like I missed the point of the lesson.

Yeah you definitely don't want to do it manually, computers are there to make tasks simpler right. You just need to use the append method of the array. Inside the braces place what it is you want to append. As below:

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

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

Also to place code in a post use 3 back ticks and the word Swift above the code and then 3 back ticks right below the code.

```Swift
    //Code goes here
```    //Then 3 back ticks like this below

Wow, thank you! You were SUPER helpful! :) I knew that I was missing something.

And thanks for the tip on putting code in a comment!

No problem.

Hey! I've been trying to resolve this but it's not working.

var results: [Int] = [1,2,3,4,5,6,7,8,9,10]

for multiplier in results { print(multiplier * 6)

}

the error gives me is this.. " Make sure the results array contains the first 10 multiples of 6" Where am I doing it wrong?
