1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

#include <iostream.h> #include <iomanip.h> #include <conio.h> const float cTaxRate = 8.50; int main () { cout << "\n Enter number of items sold: "; int quantity; cin >> quantity; cout << " Enter the unit price: "; float unitPrice; cin >> unitPrice; cout << " Enter the Discount Rate (Percent): "; float discountRate; cin >> discountRate; float subTotal = quantity * unitPrice; float discountAm = subTotal * discountRate / 100.0; float subTaxable = subTotal - discountAm; float taxAm = subTaxable * cTaxRate / 100.0; float total = subTaxable + taxAm; cout << fixed; cout << setprecision(2); cout << showpoint; cout << "\n Quantity sold: " << setw(6) << quantity << endl; cout << " Unit Price of items " << setw(9) << unitPrice << endl; cout << " -------------\n"; cout << "Subtotal : " << setw(9) << subTotal << endl; cout << "Discount : -" << setw(9) << discountAm << endl; cout << "Discounted Total: " << setw(9) << subTaxable << endl; cout << "Sales Tax : +" << setw(9) << taxAm << endl; cout << "Total sale : " << setw(9) << total << endl; getch(); return 0; } // main

Output:

 Enter number of items sold:          34
 Enter  the unit price:               12.89 
 Enter the Discount Rate (Percent):    7      
 Quantity sold:           34
 Unit Price of items      12.89  
             -------------
Subtotal :                 438.26  
Discount :            -       30.68 
Discounted Total:            407.58
Sales Tax :           +       34.64
