swift_lint.swift:10:35: error: cannot assign to value: '&&' returns immutable value
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.
var results: [Int] = []
for n in 1...100 {
if n % [ 2 ] != 0 && n % [ 7 ] = 0 {
print ( results )
}
}

There's a couple of issues here but you've got most of that spot on. Good work!
First, remove the square brackets from around the 2
and the 7
. Next, where you're checking if n
is a multiple of 7
using the %
operator, you want to compare to zero using double equals, not single. Change that to ==
.
Lastly, you want to append()
into the results
array inside your if
statement, not print
. Use dot notation to chain .append()
onto results
and pass in n
as the argument.
I hope that helps.
Steve.
