Hi there,

you don't need to enclose the "hi there, " with \(), this notion is used for injecting variable variable into the String (String interpolation).

let name = "Utsah"
let greeting = "Hi there, \(name)."

This would be suffice.

Thanks, but when I answer the second question in this way I get an incorrect answer.

let name = "bob" let greeting = "Hi there, (name)." let finalGreeting = "(greeting) How are you?"

Yes, second part strictly required that you use String concatenation to combine two string together; that's you need to use the plus sign + to combine 2 strings into one.

// Enter your code below
let name = "Utsah"
let greeting = "Hi there, \(name)."
let finalGreeting = greeting + " How are you?"  // String concatenation

In this task I guess you should try using interpolation instead of concatenation. Try with this code below:

let name = "Utsah"
let hello = "Hi there"
let greeting = "\(hello), \(name)."
