Question

This is in c programming using functions in visual studios

Carpet Jolb A carpeting company wants to estimate what it will cost a customer to have a room carpeted. They can carpet 65 sq. ft. of room space in 4 hours, and they charge $25.00 per hour as their labor rate Write a program to ask the user for the length of the room (in inches) to be carpeted, the width of the room (in inches) to be carpeted, and the price of a square foot of carpeting. For both the length and width, make sure the number entered is a non-zero positive number, and continue to ask the user for the value until a valid number is entered. For the price of a square foot of carpeting, make sure that the price is between $1.00 and $10.00 inclusive, and continue to ask for the price until a valid number is entered. Then, using 5 different functions, calculate The square footage of the room The number of hours required to carpet the room The price for the carpet to cover the room The labor charges to carpet the room The total cost to carpet the room Create global constants for: The number of square feet that can be carpeted in 4 hours (65) The number of hours required to carpet 65 sq. ft. (4) The labor rate (25.00) The The maximum carpet price (10.00) minimum carpet price (1.00) Any other numbers used in your program The program will display: The square footage of the room The number of hours to carpet the room The price for the carpet The labor charges The total cost to carpet the room Hints DO NOT pre-calculate the number of square feet that can be carpeted in 1 hour-use the 2 constants (of 65 and 4) and let the program calculate the number (in case a team of installers is hired that can carpet more than 65 square feet in 4 hours) Valiation error messages are indented 3 spaces Have a blank line between the inputs and the output Functions, just as the main() program, should have comments .Value-returning functions should not get input or display output Watch out for integer division Don't forget the function prototypes (if necessary) .Don't forget the blank line before 'Press any key to continue..."
