    Console.WriteLine(); 
 
 
    resD = ob.ovlDemo(1.1, 2.32);  
    Console.WriteLine("Result of ob.ovlDemo(1.1, 2.32): " + 
                       resD);  
  }  
}

No parameters

One parameter: 2

Two parameters: 4 6
Result of ob.ovlDemo(4, 6): 10

Two double parameters: 1.1 2.32
Result of ob.ovlDemo(1.1, 2.32): 3.42
