how to compile this code

when I tried this it says this all the time

// Enter your code below
let firstValue: Int = 2
let secondValue: Int = 4
let product = firstValue * secondValue
let output : String = " \(firstValue)* \(secondValue)  "

Hi Pankha, you've got everything right except the string interpolation syntax. The product constant already calculated the value for you, so you don't need any operator symbols in the string literal. try this...

let output = " The product of \ (firstValue) times \ (secondValue) is \ (product)"

Side note: If you want; you can leave off specifying the type in your declarations. e.g.. Int, and String. Swift will use Type Inference to deduce the Type depending on what values you declare.

Hope this helps!!
