String interpolation output

Can someone help please, The question states "Using string interpolation, create a literal string that describes the operation that we just performed. For example, given following values for firstValue ,secondValue and product respectively: 2,4,8. The string should read: The product of 2 times 4 is 8. Assign this string to a constant named output." If someone can help you are greatly appreciated.

let firstValue: Int = 2
let secondValue: Int = 4

let product: Int = 2 * 4
let output = " "

There a couple changes to make to your code.

First instead of using the values of "firstValue" and "secondValue" to work out "product" you would just use the actual variable instead.

Second the output variable needs to be an interpolated string where you use the variables content without having to find out what that is and writing that yourself. That is done by using "\(variableName)".

Overall it should look like this:

let firstValue: Int = 2
let secondValue: Int = 4

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

Wow thank you
