C# prob!

using System;

class TestClass
{
 public static void IsBigger(int a, int b, out bool isOk)
 {
 isOk = (a>b); //erste zuweisung = intitialisierung
 }

 public static void Main()
 {
 bool isOk; //nicht initialisiert
 int a;
 int b;
 a = Console.ReadLine().ToInt32();
 b = Console.ReadLine().ToInt32();

 IsBigger (a, b, out isOk);

 Console.WriteLine("Ergebnis a>b: {0}!", isOk);
 }
}
