You are working as the IT support person for an electrician. The electrician has asked you to create a program that generates a report to show the month’s customers, the total number of customers, and the amount owed across all customers. Each customer record contains a customer number, customer name, number of kilowatt hours used (up to, but not including 1000.0) and the amount owed. The amount owed is based on the number of kilowatt hours used based on the following rate schedule: Number of Kilowatts Used Cost 0.0 -199.9 $0.11 per kilowatt 200.0+ $0.08 per kilowatt Your program should gather the input data from the user. Then your program should calculate and print the each customer’s record and amount owed on a weekly payroll report. All input data and calculated amounts should appear on the report. The total amount owed and total number of customers should appear at the end of the report. When there are no customers, an error message should appear instead of a report. You may assume the customer number and customer name have already been validated and will never included an empty value.
