7.8.2.Demonstrate method overloading: different number of parameters
using System; 
 
class Overload {  
  public void ovlDemo() {  
    Console.WriteLine("No parameters");  
  }

    Console.WriteLine("One parameter: " + a);  
  }  
  
  // Overload ovlDemo for two integer parameters.  
  public int ovlDemo(int a, int b) {  
    Console.WriteLine("Two parameters: " + a + " " + b);  
    return a + b; 
  }  
  
  // Overload ovlDemo for two double parameters.  
  public double ovlDemo(double a, double b) { 
    Console.WriteLine("Two double parameters: " 
                       a + " "+ b);  
    return a + b;  
  }  
}  
  
class MainClass {  
  public static void Main() {  
    Overload ob = new Overload();  
    int resI; 
    double resD;      
  
    // call all versions of ovlDemo()  
    ob.ovlDemo();   
    Console.WriteLine()
 
    ob.ovlDemo(2);  
    Console.WriteLine()
 
    resI = ob.ovlDemo(46);  
    Console.WriteLine("Result of ob.ovlDemo(4, 6): " 
                       resI);  
    Console.WriteLine()
 
 
    resD = ob.ovlDemo(1.12.32);  
    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
