Spot the error
This Swift code contains one error – can you select the line that is incorrect?
Tip: You should mentally run the code from top to bottom, meaning that if line 3 says an integer should be returned and line 10 tries to return a string, line 10 is the wrong one.
func titleForPage(num: Int) -> String { result: String = "Turning to page \(num)..." if num < 10 { result += "The title is Introduction" } else if num < 20 { result += "The title is Reviews" } else if num < 30 { result += "The title is Features" } else { result += "The title is Tutorials" } return result}print(titleForPage(num: 3))
