Treehouse TeacherHi Marco! I can see that you've worked on this. We use the backslash and parentheses when we want to insert the value of a variable into that spot inside a string literal. A string literal is simply a set of characters inside quotation marks. In your code, "marco" is a string literal.
Also, challenges are very strict and any string they get back must match to the letter. This includes capitalization and punctuation. Your "hi there" should actually be "Hi there, " with a comma and space. Take a look:
let greeting = "Hi there, \(name)"
This will assign the string "Hi there, marco" to the constant greeting. If we had left off the backslash and parentheses from the name variable and had this "Hi there, name" and then tried to print out greeting
it would print out "Hi there, name" instead of "Hi there, marco".
Hope this helps clarify things!

- "Hi there " is a literal string so does not need the (). Just leave it in quotes.
- Name was perfectly done, except that you used separate "" around it. It should just be one large "".
- You can read Apple's explanation of Strings here.
// Enter your code below
let name = "Marco"
let greeting = "Hi there, \(name)"
I recommend you rewatch the video at 10:19. If you have questions on the second step, post below.

419 PointsIn this task we're going to declare two strings. First, declare a constant named name and assign to it a String containing your name.Second, declare a constant named greeting. Set the value of greeting to an interpolated string that combines "Hi there, " with the string stored in the name constant.As an example, the final value of greeting could be "Hi there, Linda
