You've got the loop correct; the last part of the loop code needs to be the increment of counter
, as you have done - just put that on a separate line without the square brackets.
Now, the first line inside the loop needs to add an element of numbers
into the accumulative variable named sum
.
How to access numbers
? Use counter
inside square brackets, like numbers[counter]
. Use +=
to add numbers[counter]
into sum
then increment counter
as above.
Does that make sense?
Steve.
