Code Error

I can not find my symtax problem.

operators.swift 
var results : [int] = []

for n in 1...100 {
    // Enter your code below
    if (( n % 7 == 0)  &&  (n % 2 !=0 ))
    {
       result.append (n)
       n+=1    

    } else { n+=1 } 
    // End code 
}

Hello Aramik. I think I've found the syntax error. You have too many parentheses in the if conditional -

((n & 7 == 0) && (n % 2 != 0))

try this: (n & 7 == 0) && (n % 2 != 0)

Also, the [int] should have a capital I(case sensitive), so put [Int].

The third error is the append value statement. The parentheses must be directly after append without spaces. Make sure to add an s to result, so that it matches the variable called at the top. It should look something like this:

results.append(n)

As far as the n+=1 & else statement, the two are not necessary, but shouldn't cause an error if not removed.

Hope this was helpful.

  1. There is no need for parentheses in Swift
  2. Add an s on result
  3. You do not need n += 1
var results: [Int] = []

for n in 1...100 {
    // Enter your code below

    if n % 7 == 0 && n % 2 != 0 {
      results.append(n)

    }

    // End code 
}
