For Example: Program to demonstrate arithmetic operators.

using System;

usingSystem.Collections.Generic;

usingSystem.Text;

namespace Program

{

class Program

   {

static void Main(string[] args)

        {

int Num1, Num2, result;

char option;

Console.Write("Enter the First Number : ");

            Num1 = Convert.ToInt32(Console.ReadLine());

Console.Write("Enter the Second Number : ");

            Num2 = Convert.ToInt32(Console.ReadLine());

Console.WriteLine("---------------------------------------");

Console.WriteLine("Main Menu");

Console.WriteLine("1. Addition");

Console.WriteLine("2. Subtraction");

Console.WriteLine("3. Multiplication");

Console.WriteLine("4. Division");

Console.WriteLine("---------------------------------------");

Console.Write("Enter the Operation you want to perform : ");

option = Convert.ToChar(Console.ReadLine());

switch (option)

            {

case '1':

result = Num1 + Num2;

Console.WriteLine("The result of Addition is : {0}", result);

break;

case '2':

result = Num1 - Num2;

Console.WriteLine("The result of Subtraction is : {0}", result);

break;

case '3':

result = Num1 * Num2;

Console.WriteLine("The result of Multiplication is : {0}", result);

break;

case '4':

result = Num1 / Num2;

Console.WriteLine("The result of Division is : {0}", result);

break;

default:

Console.WriteLine("Invalid Option");

break;

            }

Console.ReadLine();

        }

     }

}
