The website shows that there is an error in this program

Anything wrong in this program? Xcode shows the result correctly, but the website did not accept my program. I am sharing my program with you all. Can anyone please help me out.

var results: [Int] = []

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

results += [7,21,35,49,63,77,91]

Hi there! While the resulting array would be correct, the way you're doing it does not meet the challenge specifications. In your loop you're printing the value of n. However, the challenge explicitly states that the number should be appended to the array inside the loop if it meets the specifications (odd and evenly divisible by 7). No printing is required for this challenge. Try this again by using the append() method to append the number to the existing empty array. Good luck! :sparkles:

I cannot perform this operation using append() as there are many numbers and moreover the code challenge says that (odd numbers and multiple of 7). So the values which I got are [7,21,49,63,77,91].

without using the print(n) operation, I cannot get the values for (odd and multiples of 7). If possible can you please share your program.

Thank you

Hi again! I'm not sure why you're unable to use the append as described, so I'll show my code. I would advise reviewing any videos covering anything you do not understand in this code.

var results: [Int] = []

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

Happy coding! :sparkles:

Karthik Mada No. I've never done the soccer project as I'm neither a Techdegree student nor graduate.

That being said, receiving code for a project used for the Techdegree and using it might violate Treehouse's TOS in regards to academic dishonesty.

You can view the Techdegree Program's Code of Conduct under section 10 at this link.

Good luck! :sparkles:
