Sum and Product--program logic

. Create the logic for a program that continuously prompts a user
for a numeric value until the user enters 0.
2. The application passes the value in turn to a method that
computes the sum of all the whole numbers from 1 up to and
including the entered number. Example if the number entered is
4 the displayed value would be 10 (1+2+3+4).
3. Also to a method that computes the product of all the whole
numbers up to and including the entered number. Example if
the number entered is 4 the displayed value would be 24
(1*2*3*4).
