Hi guys. HELP please.I have no idea how to write code in this challenge. :(
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"
var results: [Int] = []
for n in 1...100 {
}
var results: [Int] = []
for n in 1...100 {
// Enter your code below
if n {
}
// End code
}

- You first need to check if the number is a multiple of 7, you do this using the modulus operator
- You also need to check if the number is odd, you also use the modulus operator here
- If both conditions are met using && you simply append the value of n
var results: [Int] = []
for n in 1...100 {
// Enter your code below
if n % 7 == 0 && n % 2 != 0{
results.append(n)
}
// End code
}
