      try { 
        Console.WriteLine(numer[i] + " / " + 
                          numer[i] + " is " + 
                          numer[i]/d);

      catch (DivideByZeroException) { 
        // catch the exception 
        Console.WriteLine("Can't divide by Zero!"); 
      } 
      catch (IndexOutOfRangeException) { 
        // catch the exception 
        Console.WriteLine("No matching element found."); 
        throw; // rethrow the exception 
      } 
    } 
  }   
   
}

Can't divide by Zero!
Can't divide by Zero!
No matching element found.
Fatal error -- program terminated.
