let months = [1, 2, 3] for month in months { if(month == 1){ println("January") } else if(month == 2){ println("February") } else if(month == 3){ println("March") } }

Courses Plus Student 2,294 Pointsfor the if statement challenge all you need to do is the for-in with the if , else if and else like so.
for month in months { if month == 1 { println ("January") } else if month == 2 { println ("February") } else { println ("March") } } Always make sure you have the same number of open and closed curly braces.

let months = [1,2,3]
for month in months{
if (month == 1) {
println("January")
}
else if (month == 2)
{
println("February")
}
else{
println("March")
}
}

Courses Plus Student 393 PointsBut if more elements are added to the array, say 4,5,6 it should not print March, thus I had it in an if else statement to future proof the desired functionality while abiding to the instructions. Does SWIFT "require" an else statement in an if/else ? If it does not then I would believe the quiz is wrong.

1,135 PointsI get what you're saying but remember how the [if, else if ,else ] statements work . when you said if the condition could true or false so if it is true execute this code if not return what i have in the else :when it comes to two conditions.
when you have more condition ,for example " a million conditions" the last one should be an else because every case before that case is not true so the last condition is true .. that is it i Hope this help.

For example:
let months = [1,2,3]
for month in months{
switch(month){
case 1:
println("January")
case 2:
println("February")
case 3:
println("March")
}

Courses Plus Student 393 PointsI totally agree, but the exercise during one of the modules specifically said to use if/else statements.

1,135 PointsIt does how many condition you the last one should always else because every case before the last did not work therefore the last it is a must
