1,894 PointsI am having difficulty getting my number from the array and adding it
I am using while loops and am trying to get a value from an array and add it to get a total sum for all of the numbers in the array.
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter
while counter < 7 {
print(counter)
counter += 1
}
while counter < numbers.count {
sum += numbers[counter]
counter += 1
}

6,885 PointsWhy are you running with 2 while loops at the same time that affect the same objects?
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
//This will only increment the counter, you should do a repeat here instead of while.
while counter < 7 {
print(counter)
counter += 1
}
ex:
repeat{
counter += 1
print(counter)
sum += numbers[counter]
}while counter < numbers.count

8,568 PointsI think you're looking for something more like this. In this while loop counter will never exceed the range of the list "numbers" and it and sum will be incremented up each iteration.
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
while counter < numbers.count {
sum += numbers[counter]
counter += 1
}
print(sum)
