OUTPUT:-



Swap two values using call by reference .

a) Create a method using reference parameter to calculate square of no.

b) Create a class by name decompose that separates the integer no and fractional part of given floating point no.


namespace Swap{ class Swapping { class Swap { public void swap(ref int a, ref int b) { int t; t = a; a = b; b = t; }

static void squareRef(ref int refParameter) { refParameter *= refParameter; } public class SwapDemo { public static void Main() { Swap ob = new Swap(); int x = 10, y = 20; Console.WriteLine("X and Y Before call: " + x + " " + y); ob.swap(ref x, ref y); Console.WriteLine("X and Y After call: " + x + " " + y); int arg; arg = 5; squareRef(ref arg); Console.WriteLine("Square Of a Number is :"+arg); Console.Read(); } } } }}
