Write a C program that calculates a customer water bill. The water bill includes RM 5.00 basic cost and cost for water usage with rate of RM 1.10 per thousand liter. Water usage is calculated by subtracting current meter reading with previous month meter reading (meter is read in thousand liter unit).Your program should check whether there is an unpaid bill. If the balance of unpaid bill is greater than 0, RM 2.00 fine is charged together with the unpaid bill and this will be included in the current monthly bill. The program will also calculate the bill collected for the day. The program will continue if user enters y- yes, else it will stop and display the collection for the day. Your program should use these functions :

1.calc_usage_cost – accepts previous and current meter reading, returns usage cost.

2.calc_unpaid_cost – accepts unpaid bill, returns unpaid cost.

3.calc_total_bill – accepts usage cost and unpaid cost, returns total bill.

4.print_bill – accepts account number and total bill.
