collection and control flow

Question

var results: [Int] = [
1,2,3,4,5]
let multiplier = 1,2,3,4,5,6
for number in 1...10 {
print("(number) times 10 is equal to \
    (number * 10)")
help for solution guys
```loops.swift
// Enter your code below
var results: [Int] = [
1,2,3,4,5]
let multiplier = 1,2,3,4,5,6
for number in 1...10 {
print("(number) times 10 is equal to \
    (number * 10)")
```

Let's go through the assignment and the code step by step:
Your task for this step is to create a for in loop that iterates over a range. Multiplication tables typically range from 1 to 10 (with 10 included) so the range you are iterating over should go from 1 to 10.
For in loops also define a constant that temporarily stores the value in the iteration process. For the loop you're writing, name this constant multiplier.
```Step1.swift
// Empty array of ints
var results: [Int] = []
// constant that temporarily stores the value
// in the iteration process = multiplier
for multiplier in 1...10 { //range you are iterating over should go from 1 to 10
}
```
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
```Step2.swift
var results: [Int] = []
for multiplier in 1...10 {
  // Inside the body of the loop, we're going
  // to use the multiplier to get the multiple of 6.
  results.append(multiplier * 6)
}
```
Hope that helps :)
