Challenge Task 2 of 2

Given these two values we just declared, we want to compute the product and print out the product in a formatted string.

Step 1: Declare a constant named product and assign the result of multiplying firstValue and secondValue together. (To multiply two values, a and b, we write a * b).

Step 2: Using string interpolation, create a string literal that describes the operation we just performed. For example, given the 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.

answar // Enter your code below let firstValue = 2 let secondValue = 4

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

types.swift 
// Enter your code below
let firstValue = 2
let secondValue = 4

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