How would I retrieve a value and then add it to the variable sum
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
while counter < 7{
sum = counter + numbers[counter]
counter++
}
// Enter your code below

10,040 PointsHi Tejas Pulavarti, Lets take a look at your code for a bit. after while we need to include (). Also, we don't want to hard code the number 7 because the array can change. What if you add more numbers to the array or take away numbers. You will need to change the number every time you make a change to the array. Instead we use numbers.count this will count the numbers in the array for you.
I have provided my solution to this task below your code.
Your Code:
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
while counter < 7{
sum = counter + numbers[counter]
// on this section above we are trying to add all the numbers of the array. We don't want to use the counter because the counter will change every time it goes through the loop. instead we use sum. (sum = sum + number[counter] or sum += number[counter])
counter++
}
// Enter your code below
Solution:
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++
}
