In this exercise, we’ll begin our tour of structures in Swift. You’ll usually hear them called “Structs”.

struct Student {
  
}

let name: String

var grade: Int
var pet: String?

Student

Student(name: "Chris", grade: 49, pet: "Mango")

let chris = ...

let sam = Student(name: "Sam", grade: 99, pet: nil)
let catie = Student(name: "Catie", grade: 75, pet: "Ozma")

func getPassStatus(

func getPassStatus(lowestPass: Int = 50) -> Bool {
  grade >= lowestPass
}

func getPassStatus(lowestPass: Int = 50) -> Bool {
  grade >= lowestPass
}

func getPassStatus(lowestPass: Int = 50) -> Bool {
  grade >= lowestPass
}

chris.

chris.getPassStatus()

func earnExtraCredit() {
  grade += 10
}

mutating func earnExtraCredit...

chris.earnExtraCredit()

var chris = Student...

chris.getPassStatus()

let evilCatie

let evilCatie = catie

evilCatie.grade = 100
evilCatie.pet = "Mustachioed Ozma"

var evilCatie = catie

catie
evilCatie
