Create a C program that contains a function that computes the final price for a sales transaction and return that value to a calling method.
The function requires three arguments: product price, salesperson commission rate and customer discount rate. A product final price is the original price plus the commission amount minus the discount amount; the customer discount is taken as a percentage of the total price after the salesperson commission has been added to the original price.
Write a main( ) method that prompts the user for the price of an item, the salesperson commission expressed as a percentage, and the customer discount expressed as a percentage and that then passes the values to the function.
