Question

1. Create an Enum and call it “Item”. Declare 20 values in the Enum and name them based on your preference. Create a structure called “Order”. Declare an Item and a double for the item price. Create a structure called “Package” where it has an Order pointer, integer for the size, string for the address, package id and bill details. In the main, declare a Package and assign to it more than 3 items. Create a string returning function called “generateBillDetails” that takes a Package as constant reference and return the bill details as string. Don’t create a string variable/object in the main or outside the main to store the returned value. Store the returned string in the Package. Show the bill string on the console..C++

Sample Example:

Package ID    : #4546-786-543-06-5g

Address       : United States, The Crazy State, Porgareta, Senti-Marraia, St. 12, Villa #2

Ordered Items : Car            $2,500.00

                Chair             $60.00

                Door             $100.00

                Computer         $999.50

                Aircraft     $150,000.01

               --------------------------

                Total:       $153,659.51

A picture so it will be more clarified

Package ID    : #4546-786-543-06-5g Address       : United States, The Crazy State, Porgareta, Senti-Marraia, St. 12, Villa #2 Ordered Items : Car            $2,500.00                 Chair             $60.00                 Door             $100.00                 Computer         $999.50                 Aircraft     $150,000.01                --------------------------                 Total:       $153,659.51

Code:

#include <iostream>
#include <string>

using namespace std;

enum Item
{
   Car,
   Chair,
   Computer,
   Aircraft,
   Door,
   Bag,
   Books,
   Laptop,
   Table,
   Sofa,
   TV,
   Shoes,
   Dress,
   Jeep,
   HeadPhone,
   Mobile,
   Purse,
   Cupboard,
   Cap,
   Hammer
};

string itemarr[] =
{
   "Car",
   "Chair",
   "Computer",
   "Aircraft",
   "Door",
   "Bag",
   "Books",
   "Laptop",
   "Table",
   "Sofa",
   "TV",
   "Shoes",
   "Dress",
   "Jeep",
   "HeadPhone",
   "Mobile",
   "Purse",
   "Cupboard",
   "Cap",
   "Hammer"
};

struct Order
{
   Item item;
   double price;
   Order(int num, double p)
   {
       item = (Item)num;
       price = p;
   }
};

struct Package
{
   Order* orderptr;
   int size;
   string address;
   string packId;
   string billDetails;
};

string generateBillDetails(const Package& pack)
{
   string billDetails;
   billDetails += "Package ID :" + pack.packId + "\n";
   billDetails += "Address : " + pack.address + "\n";
   billDetails += "Ordered Items : ";
   double total = 0.00;
   for (int i = 0; i < pack.size; i++)
   {
       billDetails += itemarr[(int)pack.orderptr[i].item] + " " + to_string(pack.orderptr[i].price) + "\n";
       total += pack.orderptr[i].price;
   }
   billDetails += "---------------------------\n";
   billDetails += "Total : "+to_string(total) + "\n";
   return billDetails;
}
int main()
{
  
   Package pack;
   pack.packId = "#4546-786-543-06-5g";
   pack.address = "United States, The Crazy State, Porgareta, Senti-Marraia, St. 12, Villa #2";
   pack.orderptr = new Order[5]{ {(Item)0,2500.00},{(Item)1,60.00},{(Item)2,100.00},{(Item)3,999.50},{(Item)4,150000.00} };
   pack.size = 5;
   pack.billDetails = generateBillDetails(pack);
   cout << "Bill Details : \n"<<pack.billDetails;
   return 0;
}

OUTPUT:

Microsoft Visual Studio Debug Console Bill Details Package ID #4546-786-543-06-5g Address United States, The Crazy State, Porgareta, Senti-Marraia, St. 12, Villa #2 Ordered Items : Car 2500.000000 Chair 60.00000 Computer 100.000000 Aircraft 999.500000 Door 150000.000000
