Write a program that asks for the weight of a package and the distance it is to be shipped. This information should be passed to a calculateCharge function that computes and returns the shipping charge to be displayed . The main function should loop to handle multiple packages until a weight of 0 is entered.

Answer:

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

   const int WEIGHT_MIN   =    0,

             WEIGHT_MAX   =   20,

             DISTANCE_MIN =   10,

             DISTANCE_MAX = 3000;

   float package_weight,

         distance,

         total_charges;

   cout << "\nWhat is the weight (kg) of the package? ";

   cin >> package_weight;

   if (package_weight <= WEIGHT_MIN ||

       package_weight > WEIGHT_MAX)

   {

       cout << "\nWe're sorry, package weight must be\n"

            << " more than 0kg and less than 20kg.\n"

            << "Rerun the program and try again.\n"

            << endl;

   }

   else

   {

       cout << "\nDistance? ";

       cin >> distance;

       if (distance < DISTANCE_MIN ||

           distance > DISTANCE_MAX)

       {

           cout << "\nWe're sorry, the distance must be\n"       << "within 10 and 3000 miles.\n"

                << "Rerun the program and try again.\n"

                << endl;

       }

       else

       {

            if (package_weight <= 2)

               total_charges = (distance / 500) * 1.10;

           else if (package_weight > 2 &&

                   package_weight <= 6)

               total_charges = (distance / 500) * 2.20;

           else if (package_weight > 6 &&

                   package_weight <= 10)

               total_charges = (distance / 500) * 3.70;

           else if (package_weight > 10 &&

                   package_weight <= 20)

               total_charges = (distance / 500) * 4.80;

           cout << setprecision(2) << fixed

               << "Total charges are $"

               << total_charges

               << "\nFor a distance of "

               << distance

               << " miles\nand a total weight of "

               << package_weight

               << "kg.\n"

               << endl;

       }

   }
