I wrote this code and just realized I need to put it into at
least 6 different functions and I don't know how. No specific ones
but recommended is: Read Data, Calculate Installation Price,
Calculate Subtotal, Calculate Total, Print -> 1) Print
Measurements & 2) Print Charges. Can somebody help?
#include <stdio.h>
// Function Declarations
int length, width, area, discount;
int main ()
{
// Local Declarations
double price, cost, charge, laborCharge, installed, amtDiscount,
subtotal, amtTax, total;
const double tax...
