namespace MySpecifiers {
   class Demo {
      protected string name = "Website";
      protected void Display(string str) {
         Console.WriteLine("Tabs: " + str);
      }
   }

   class Test : Demo {
      static void Main(string[] args) {
         Test t = new Test();
         Console.WriteLine("Details: " + t.name);
         t.Display("Product");
         t.Display("Services");
         t.Display("Tools");
         t.Display("Plugins");
      }
   }
}
