972 PointsI don't understand how to pass this task
Task 2 of 2 asks: Now that we have the while loop set up, it's time to compute the sum! Using the value of counter as an index value, retrieve each value from the array and add it to the value of sum.
For example: sum = sum + newValue. Or you could use the compound addition operator sum += newValue where newValue is the value retrieved from the array.
// Code provided
let numbers = [2,8,1,16,4,3,9] var sum = 0 var counter = 0
// I passed the first part with this piece of code // Enter your code below while counter <= 0 { // < ---- I passed the first part with this piece of code print("sum") counter += 9 }
while counter > numbers.count { sum = sum + numbers[counter] counter ++ // <---- This is my second piece of code after looking through help... no luck }
This is really frustrating, I can't get a pass no matter what. Is this for real?
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below
while counter <= 0 {
print("sum")
counter += 9
}
while counter > numbers.count {
sum = sum + numbers[counter]
counter ++
}

while counter < numbers.count { sum += numbers[counter] counter += 1 }

let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below
while counter < numbers.count {
sum += numbers[counter]
counter += 1
}
