// Enter your code below
let name = "wilian"

184 PointsHello,
your code should look like this: let name = "sam" let greeting = "Hi there, \ (name)" let finalGreeting = greeting + "." + "How are you?"

13,515 PointsEssentially the task is asking you to demonstrate the two essential concepts of string manipulation - interpolation and concatenation. The greeting constant uses your name (declared in the constant 'name') and "interpolates" it into a string so as to read "Hi there, Willian". The finalGreeting constant uses the greeting constant, which reads ("Hi there, Willian"), and links, or "concatenates", the phrase "How are you?", in order to make the final output read "Hi there, Willian. How are you?"
let name = "Willian"
let greeting = "Hi there, \(name)"
let finalGreeting = greeting + ". How are you?"
