}
class Student : Person {
   private string code = "N.A";
   private string name = "N.A";
   private int age = 0;
   // Declare a Code property of type string:
   public string Code {
      get {
         return code;
      }
      set {
         code = value;

   }
   public override string ToString() {
      return "Code = " + Code +", Name = " + Name + ", Age = " + Age;
