using System;//from ww w.  j av a2s .  co m

public struct ComplexNumber

   public double Real { get; }

   // overload the subtraction operator
   public static ComplexNumber operator-(ComplexNumber x, ComplexNumber y)

   // overload the multiplication operator
   public static ComplexNumber operator*(ComplexNumber x, ComplexNumber y)

   {
      Console.Write("Enter the real part of complex number x: ");
      double realPart = double.Parse(Console.ReadLine());
      Console.Write("Enter the imaginary part of complex number x: ");
      double imaginaryPart = double.Parse(Console.ReadLine());
      var x = new ComplexNumber(realPart, imaginaryPart);

      // prompt the user to enter the second complex number
      Console.Write("\nEnter the real part of complex number y: ");
      realPart = double.Parse(Console.ReadLine());
      Console.Write("Enter the imaginary part of complex number y: ");
      imaginaryPart = double.Parse(Console.ReadLine());
      var y = new ComplexNumber(realPart, imaginaryPart);

      // display the results of calculations with x and y
      Console.WriteLine();
      Console.WriteLine($"{x} + {y} = {x + y}");
      Console.WriteLine($"{x} - {y} = {x - y}");
      Console.WriteLine($"{x} * {y} = {x * y}");
