namespace testdesignlibrary

{

   public class test

   {

      public static void main()

      {

         string s1 = "12345";

         string s2 = "12345";

         string s3 = "12345";

         console.writeline("changing pointer - passed by value:");

         console.writeline(s1);

         referencetypesandparameters.badpasstheobject (s1);

         console.writeline(s1);

         console.writeline("changing pointer - passed by reference:");

         console.writeline(s2);

         referencetypesandparameters.passthereference (ref s2);

         console.writeline(s2);

         console.writeline("passing by return value:");

         s3 = referencetypesandparameters.betterthanpassthereference (s3);

         console.writeline(s3);

      }

   }

}
