How do we set a value to a constant by interpolating a stored constant and a value not assigned yet to any constant ?

let name = "Patrick" let greeting = "(hi there,), (name)"

let name = "Patrick"
let greeting = "hi there,", "\(name)"

This is how you do it :)

let name = "Patrick"
let greeting = "Hi there, \(name)" 

Just write whatever doesn't already exist in a constant between quote marks like you would a regular string:

let greeting = "Hi there, " 

Then insert an existing value by calling it between /() :

let greeting = "Hi there, /(name)" //call the name of the constant (which in this case also happens to be "name") to SUBSTITUTE the constant's value into the string! 

The results will be: "hi there, Patrick"

Let me know if this helped. :)

You almost got it.

Name should be inside the same quotations as "Hi there, ".

let name = "Nate" let greeting = "Hi there, (name)"
