                Console.WriteLine("**** Enter the first number *****");
                int x = Convert.ToInt32(Console.ReadLine());
                Console.WriteLine("**** Enter the second number *****");
                int y = Convert.ToInt32(Console.ReadLine());
                Console.WriteLine("**** Enter 1 for addition  *****");
                Console.WriteLine("**** Enter 2 for subtration  *****");
                Console.WriteLine("**** Enter 3 for multification  *****");
                Console.WriteLine("**** Enter 4 for divition  *****");
                int z = Convert.ToInt32(Console.ReadLine());
                switch (z)
                {
                    case 1:
                        Console.WriteLine(x + y);
                        break;
                    case 2:
                        Console.WriteLine(x - y);
                        break;
                    case 3:
                        Console.WriteLine(x * y);
