Would Anyone Like to do This?
I am having trouble doing the following C project...if anyone is interested in helping me fulfil the following conditions for the code below, i would be willing to compensate them for their time. here are the specifications for the project. The code below is the code that is being modified. it compiles and runs. PM me if you would like to help. Thanks, bradc0101.
Modify Project 3 in the following way:
The very first thing and only once in the program: prompt the user for a SEED for the random number generator.
Design a looping structure that will allow the user to create multiple bills; in other words, keep running the program until I let you know I'm done.
Use a random number to get the discount instead of prompting the user for this value. The discount should range from 0 to 50.
Prompt the user for the Length, Width, and Price.
Test your input for validity: the Length should be a positive number; it should also be at least 2 feet and no more than 50. If I enter a number less than 2 or larger than 50, prompt me to reenter the length until the value is within the valid range.
Test your input for validity: the Width should be a positive number; it should also be at least 2 feet and no more than 30. If I enter a number less than 2 or larger than 50, prompt me to reenter the width until the value is within the valid range.
Test your input for validity: the Price should be a positive number; it should also be at least $1.00 and no more than $20.00. If I enter a number less than 1.00 or larger than 20.00, prompt me to reenter the price until the value is within the valid range.
Use a menu allow the use to see the specific charges they want to see, not the entire bill.
Sample menu:
**************************************************
* SELECT 1 for the AREA *
* SELECT 2 for the CARPET COST *
* SELECT 3 for the LABOR CHARGE *
* SELECT 4 for the INSTALLED PRICE *
* SELECT 5 for the DISCOUNT AMOUNT *
* SELECT 6 for the TAX *
* SELECT 7 for the TOTAL *
* SELECT 9 for another bill *
* SELECT 0 to quit *
**************************************************
Display the requested output until the user wants to go back to the menu and select something else. When the user selects 9 to create another bill, you must return back to the beginning of the program and prompt the user for a new Length, Width, and Cost.
When the user selects 0 to quit, gracefully exit the program.
You will use functions and addresses as in the original assignment, but you may combine several functions that may seem related to you. Your main should not be cluttered and full of activity. It should be a driver (like a supervisor) calling the other functions in the proper order and sending the values or addresses those functions need to get their jobs done.
