Use a while loop to process user entered numbers.
Inform the user to enter a positive number to be added to the total or -1 to end.
With each iteration of the loop, add the user entered value to a running total.
End the loop when the user enters -1 and do not add that value to the running total.
Once the loop ends, print the total of the numbers entered, (excluding the sentinel value -1.)
Define the appropriate variables needed.
