Question:An enum is defined in a program as follows:
         [Flags]
        public enum Permissions
        {
            None = 0,
            Read = 1,
            Write = 2,
            Delete = 4
        }

What will be the output of the following Main program (which has access to the enum defined above) in this C# console application (Assume required namespaces are included) :

static void Main(string[] args)
{
    var permissions = Permissions.Read | Permissions.Write;
    if ((permissions & Permissions.Write) == Permissions.Write)
    {
        Console.WriteLine("Write");
    }
    if ((permissions & Permissions.Delete) == Permissions.Delete)
    {
        Console.WriteLine("Delete");
    }
    if ((permissions & Permissions.Read) == Permissions.Read)
    {
        Console.WriteLine("Read");
    }
    Console.ReadLine();
}
