Question
The High Fashion Department Store wants a program written to produce
its monthly bills. Input to the program will be the customer number,
the number of the department in which that item was purchased, the item
number, and the amount of the purchase. There are four departments
numbered 1 through 4. On all purchases of $10.00 or more in departments
1 and 2 , the customer receives a 5 percent discount. On all purchases
of $25.00 or more in departments 3 and 4, the customer receives an 8
percent discount. Totals are to be produced for each department and
for each customer. Sales tax of 7 percent is paid on the net total for
the customer. Also a service charge is added to the bill if the amount
of the bill is less than $100.00. The service charge is 10 percent of
the net bill before the sales tax is added if the total is less than
$50.00. Otherwise, the service charge is 5 percent. The bill for each
customer is to be printed on a separate page. (You need a counter to
keep track of the number of print lines used.)
You have to use at least two functions for this assignment.
Make sure error checks are performed on the input data.
