i did not understand the question on page 2/2 for this task..

code:

let name = "yusuf." let greeting = "Hi there," let interpolatedgreeting = "(greeting) (name)" let finalGreeting = "How are you?" let concatenatedfinalgreeting = interpolatedgreeting + finalGreeting

So what they are trying to teach in this challenge is the two ways of manipulating strings. Consider the code below.

let name = "yusuf"  // Here you declared your name correctly.
let greeting = "Hi there, \(name)."  // The first step they show you interpolation.
let finalGreeting = greeting + " How are you?"  // The second step they show you concatenation.

Key takeaways here are:

  • When interpolating write the string as normal inside the quotes but remember to escape your values with ().
  • When concatenating remember that spaces are not inserted to be sure to include them in the quoted string.
