I put the "\n" inside the quotes for the newline character, but it won't compile. It compiled in the playground.

I had the following code:

for number in 1...7 {
  println("\(number) times 7 is \(number * 7)\n")
}

which I tested and ran fine in the Xcode playground and would not compile in the editor here. Am I missing something? I've tried it several different ways (moving the "\n" outside the quotes, to the beginning of the statement, etc.

I am borrowing this from Stone Preston's answer to a similar question in the Forum: "Remove the new line character from the end. since you are using the println function everything will be on a separate line regardless."

for number in 1...10 {
    println ("\(number) * 7 = \(number*7)")
}

Hi Todd,

The in class editor checks for exact duplication of the anticipated answer. So even though you code works, it's not what the test was asking for.

First, get rid of the \n.

Second the question for the test was to make it in the following format "1 * 7 = 7" Can you see the difference in your output and what would the output would be in William's code above?

Hope this helps.
