Question
i need help, my program is due tommorrow!! write a c program that creates customers bills for a carpet company when the following information is given:
a. the length and the width of the carpet in feet
b. the carpet price per square foot
c. the percent of discount for each customer
The labor cost is fixed at .35 per square foot. It is to be defined as a constant. The tax rate is 8.5% applied after the discount. It is also the to be defined asa constant. The input data of a set of three integers representing the length and width of teh room to be carpeted, the percentage of the discount the owner gives to a customer, and a real number representing the unit price of teh carpet. the program is to prompt the user for this input as shown below.
Length of the room (feet)? 30
Width of the room (feet)? 18
Customer discount (percent)? 9
Cost per square foot (xxx.xx)? 8.23
The output is shown below. Be careful to align the Decimal points.
MEASUREMENT
Length XXX ft
Width XXX ft
Area XXX square ft
CHARGES
DESCRIPTION COST/SQ.FT. CHARGE
----------------------- -------------------- ---------------
Carpet XXX.XX $XXXX.XX
Labor 0.35 XXXX.XX
----------------
INSTALLED PRICE $XXXX.XX
Discount XX% XXXX.XX
-----------------
SUBTOTAL $XXXX.XX
Tax XXXX.XX
TOTAL $XXXX.XX
The program should use main and at least the six function described below:
a Read data from the keyboard. This function is to use addresses to read all data and place them in the calling functions variables.
b. Calculate values.This function calls three subfunctions. Each functionis to use addresses to store their result.
Calculate the installed price. this function calculates area, carpet cost, labor cost, and installed price. The installed price is si the cost of the carpet and teh cost of the labor.
Calculate the subtotal. Tjis function Calculates the discount and subtotal.
Calculate the total price with discount and tax. tjis function calculates the tax and the total price.
c. print the result. Use two subfunctions tp print the results: one to print the measurments; and the second to print the charges.
