In the previous set of exercises, you saw how you can work with Boolean values, and how you could use comparison operators such as less than, greater than, equal to and not equal to to compare values to each other.

let passingGrade = 50
let studentGrade = 50
let chrisGrade = 49
let samGrade = 99
let studentPassed = studentGrade >= passingGrade
let chrisPassed = chrisGrade >= passingGrade
let samPassed = samGrade >= passingGrade
chrisPassed == false
let catName = "Ozma"
// AND Operator
// &&
let bothPassed = chrisPassed && samPassed
// OR Operator
// ||
let eitherPassed = chrisPassed || samPassed
let anyonePassed = chrisPassed || samPassed || studentPassed
let everyonePassed = chrisPassed && samPassed && studentPassed
let meritAwardGrade = 90
let samHasPerfectAttendance = true
let samIsMeritStudent = samHasPerfectAttendance && samGrade > meritAwardGrade
let chrisHasPerfectAttendance = true
let chrisIsMeritStudent = chrisHasPerfectAttendance && chrisGrade > meritAwardGrade
if chrisIsMeritStudent {
else {
    print("Keep studying.")
var betterStudent: String
if samGrade > chrisGrade {
    betterStudent = "Sam"
} else {
    betterStudent = "Chris"
// Ternary conditional operator
betterStudent = samGrade > chrisGrade ? "Sam" : "Chris"
