Items Price Calculation in C#

Objective:

Write a simple program in which calculate the total amount of items that are sold. Calculate Total Price after discount.

Program:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace ItemCalc

{

    class Program

    {

        static void Main(string[] args)

        {

            int[] ItemNUM = new int[5];

            string[] ITEMName = new string[5];

            double[] unitprice = new double[5];

            int[] quantiy = new int[5];

            double[] price= new double[5];

            double discount;

            double[] Total = new double[5];

            double Sum=0;

            for (int i = 0; i < 5; i++)

            {

                ItemNUM[i] = i + 1;

                Console.WriteLine("IITEM {0}",ItemNUM[i]);

                Console.WriteLine("Enter ITEM Name");       

                ITEMName[i] = Console.ReadLine();

                Console.WriteLine("Enter unit price");

                unitprice[i] = Convert.ToDouble(Console.ReadLine());

                Console.WriteLine("Enter Quantity");

                quantiy[i] = Convert.ToInt32(Console.ReadLine());

                Console.WriteLine();

                Total[i] = quantiy[i] * unitprice[i];

                Console.WriteLine("Total Price of ITEM:{0} ={1}\n",ItemNUM[i],Total[i]);

                Sum = Sum + Total[i];

            }

            Console.WriteLine("ENter Discount in %");

            int disc =Convert.ToInt32( Console.ReadLine());

            Console.WriteLine("\nITEM \t  ITEM Name\t Unit Price \t Quantity\t Total Price\n");

            for(int i=0; i<5;i++)

            {

                Console.WriteLine("ITEM:{0} \t{1}\t\t{2}\t\t{3}\t\t{4}", ItemNUM[i], ITEMName[i], unitprice[i], quantiy[i], Total[i]);

            }

            Console.WriteLine("\nTotal Amount={0}",Sum);

            discount = Convert.ToDouble((disc / 100.0) * Sum);

            double TotalPrice = Sum - discount;

            Console.WriteLine("Amount After discount={0}",TotalPrice);

            Console.WriteLine("Please recieve the amount....!!! ");

        }

    }

}
