Courses Plus Student 683 PointsThis loop got me all loopy
In this task, we have an array of numbers and we want to compute the sum of its values.
We have a variable ,sum, that will store the value of the sum of numbers from the array.
We also have a variable ,counter, which we will use to track the number of iterations of the while loop.
Step 1: Create a while loop. The while loop should continue as long as the value of counter is less than the number of items in the array. (Hint: You can get that number by using the count property)
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below

The size of the numbers
array is accessible from its .count
property. To iterate over each element of numbers
, the while statement's conditional expression should evaluate to true so long as counter
is less than numbers.count
, and counter
should be incremented by one from within the statement's body. This incrementation should occur after any expression that accesses numbers
using the counter
value.
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
while counter < numbers.count {
// add numbers[counter] to sum
counter += 1
}
Hope this helps
