Notes for Slide 05
When using a for-statement to look at each element
of an array, the counter variable starts at zero and
the loop will end when the counter variable is no longer
less than the total number of elements.
Recall that the final element of an array is
referenced by using the total number of elements
minus one.
The ++ at the end specifies that the loop counter
variable will increment by one each time through the loop.
Thus, the variable named counter will start at 0 and
then after running statements (that are likely to
use the counter variable) the loop will run again with
the value of 1 in counter variable. The value in the
counter variable then increases to 2, 3, 4, etc. up
to the value of 9. The next time the counter variable
increments by one it will have the value of 10
which causes the loop to end.
After the loop ends, the counter variable is no
longer available.
