At this point, you should feel pretty good about working with logical operators. You’ve seen how combining them can produce a true or false value. But what if you wanted to set a value based on the result of our logical operators? Often times, you’ll want to set a variable based on a condition.

/*
// Starter code
val chrisGrade = 49
val meritAwardGrade = 90
*/
var message
var message: String
val chrisHasPerfectAttendance = true
val chrisIsMeritStudent = chrisHasPerfectAttendance && chrisGrade > meritAwardGrade
if (chrisIsMeritStudent) {
    message = "Congratulations"
}
println(message)
else {
    message = "Keep studying"
}
val samGrade = 99
val betterStudent 
val betterStudent = if (samGrade > chrisGrade) "Sam" else "Chris"
println(betterStudent)
val betterStudent = if (samGrade > chrisGrade) {
    "Sam"
} else if (samGrade < chrisGrade) {
    "Chris"
} else {
    "They have equal grades!!!"
}
