Operator Overloading in C# Class of Weight

Objective:

Write a program to add weight given in kilogram, gram and miligram by using operator overloading.

Program:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace ConsoleApplication1

{

    class weight

    {

        int kilogram;

        int gram;

        int milligram;

        public weight(int kg, int g, int mg)

        {

            kilogram = kg;

            gram = g;

            milligram = mg;

        }

        public void Display()

        {

            Console.WriteLine("The Total weight is {0} kilogram, {1} gram ,{2} milligram", kilogram, gram, milligram);

        }

        public static weight operator +(weight fd, weight sd)

        {

            int kgg, gg, mgg;

            kgg = fd.kilogram + sd.kilogram;

            gg = fd.gram + sd.gram;

            mgg = fd.milligram + sd.milligram;

            if (mgg > 9)

            {

                for (int n = mgg; mgg > 9; mgg -= 10)

                {

                    gg++;

                    if (gg > 999)

                    {

                        for (int a = gg; gg > 999; gg -= 1000)

                        {

                            kgg++;

                        }

                    }

                }

            }

            weight w = new weight(kgg, gg, mgg);

            return w;

        }

        static void Main(string[] args)

        {

            weight w1 = new weight(12, 1500, 25);

            weight w2 = new weight(25, 3665, 20);

            weight w3 = w1 + w2;

            w3.Display();

        }

    }

}

Output:
