What is the output of the following program? using System; public static class Parameter Passing { public static void Main() { int a = 4,0 = 8, c= 3; Console.WriteLine("a = {0}, b = {1},c = {2}", a, b, c); a= Methodi(cref b); Console.WriteLine("a = {0}, b = {1},c= {2}", a, b, c); Console.ReadLine(): } public static int Methodi(int x, ref int y) { Console.WriteLine("x = {0}, y = {1}", x, y); Method2(ref x, y+4); y= 9; Console.WriteLine("x = {0}, y= {1}", x, y); return 0; } public static void Method2 (refint q, int p) { q=p++; p = 2; Console.WriteLine("p = {0}, q = {1}", p. 9); }
