I have been trying to solve this code challenge and I have not been able to solve it. I had to google how to find the odd numbers and the multiples of 7. Still don't quite understand , can someone please explain?
var results: [Int] = []
for n in 1...100 {
// Enter your code below
if n % 2 == 0 && n & 7 == 0 } results.append(n)
// End code
}

Firstly, you need to check to make sure n is odd, not even. This means you need to check to see if n % 2 == 1, not 0
n % 2 == 1 // CHECKS TO SEE IF n IS ODD
Secondly, your if statement isn't structured correctly. This is the basic structure of an if statement:
if /*CONDITION - TYPE BOOL*/ {
//DO STUFF
}
In this challenge, the CONDITION is checking to make sure n is odd AND divisible by 7. Inside the body of the if statement (the place where you DO STUFF), you append n to the results array.
if n % 2 == 1 && n % 7 == 0 {
results.append(n)
}
I hope this helps!

1,489 PointsSorry this might sound silly but im still very new.. What does the & symbol mean (between n&7) I know what the && means, just a bit confused Thankyou :)

28,883 PointsActually, that was an error in my code. That should be "n%7", not "n&7". I've corrected it in my solution above. Thanks for pointing this out! (:

28,883 PointsI'm sorry, Yashim. I had an error in my code: instead of "n & 7", I should have written "n % 7". I corrected the error in the code above. Try putting that in your for loop.
