concatenating and string interpolation

Declare a constant named finalGreeting and concatenate the value of greeting with the string literal "How are you?"

PS. these are the 2 different codes a tried on at time and both were wrong

strings.swift
let name = "Aditya"
let greeting = "Hi there, \(name)."
let finalGreeting = "\(greeting) + How are you?" 


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

Hi Aditya

When interpolating, you don't need the + in your strings. When concatenating, your constant 'greeting' shouldn't be between quotes.

Try: let name = "Aditya" let greeting = "Hi there, (name)." let finalGreeting = greeting + " How are you?"

Hope this helps ;)

When using string interpolation, you need to use the correct syntax inside the string.

let name = "Aditya"
let greeting = "Hi there, \(name)" // string interpolation

let finalGreeting = greeting + "How are you?" // concatenating
