iOS Development Techdegree Student 9,702 PointsThis project had two parts, so let us break down each one.
The first part was making getting the odd numbers out of the range. You are using the correct operand, just need to look at the order of it. From Apple Developer documentation:
The remainder operator (a % b) works out how many multiples of b will fit inside a and returns the value that is left over (known as the remainder).
So to find an even number we need to take that number and make sure we have a remainder of 0, to find an odd number we have a remainder value that is not 0. This would look something like
n % 2 != 0
or
n % 2 == 1
The next part is the multiple of 7. I was able to find this using the same process as finding the odd numbers. If the number n divided by 7 == 0 then it should be a multiple of 7. That would look like this
n % 7 == 0
Then just put them both together like you did above.
if n % 0 != 0 && n % 7 == 0 {
// append to array here }
I hope that helps you. :D
