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 aquare foot c. the percent of discount for each customer The labor cost is fixed at $0.35 per sqaure foor. It is to be defined as a constant. The tax rate is 8.5% applied after the discount. It is also to be defined as a constant. The input data consist of a set of three integers representing the length and width of the room to be carpeted, the percentage of the discountthe owner gives to a customer, and a real number representing the unit price of the carpet. The program is to prompt the user for this input as shown below> Length of room (feet)? 30 Width of room (feet)? 18 Customer discount (percentage)? 9 Cost per sqaure foot (xxx.xx)? 8.23

The program's design should use the main and at least the six functions described below:

Read data from the keyboard.

a. This function is to use addresses to read all data and place them in the calling function's variables.

b. Calculate values. This function calls three subfunctions. Each function is to use addresses to store their results.

c. Print the results. Use two subfunctions to print the results: one to print the measurements and one to print the charges.

Here's my code however I get runetime errors please help. The code is in C.
