Instructions: Challenge Task 1 of 1
For this challenge, we'd like to know in a range of values from 1 to 100, how many numbers are both odd, and a multiple of 7.
To start us off, I've written a for loop to iterate over the desired range of values and named the local constant n. Your job is to write an if statement inside the for loop to carry out the desired checks.
If the number is both an odd number and a multiple of 7, append the value to the results array provided.
Hint: To check for an odd number use the not operator to check for "not even"
What is wrong with my 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
}

You just have some brackets wrong there. And you've used a single = rather than comparing with double-equals:
for n in 1...100 {
// Enter your code below
if n % 2 != 0 && n % 7 == 0 {
results.append(n)
}
// End code
}
I hope that helps.
Steve.
