3,968 PointsHow do you retrieve values and add it in the variable sum?
Instructions
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.
How do I do this?
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below
counter = 0
while counter < numbers.count{
counter += 1
for newValue in numbers{
sum = sum + newValue
}
}
