I know I'm missing something, but can anyone tell me why we do we type n % 7 == 0. I understand the n % 7 part, whats the story with the 0? Can someone please break this down for me.
var results: [Int] = []
for n in 1...100 {
// Enter your code below
if (n % 7 == 0 && n % 2 != 0) { results.append(n) }
// End code
}

2,998 PointsHi Sapho for that bit of code its purpose is to see if you have two numbers that are perfectly divisible. n is representing the 100 numbers were going to be looping through and checking. To see if two numbers are completely divisible they will have a remainder of 0. 25/5 is perfectly divisible because you have no remainder and 5 goes into 25 five times.
let example = 25 % 5
if example == 0 {
print(true)
} else {
print(false)
}
example == 0
In the code when you write out 25 % 5 == 0 you write out twenty five divided by five is equal to zero and sure enough thats a true statement. For the FizzBuzz problem you need this to check if a number is perfectly divisible by 3 or 5.
