    • 4. Which of the following statements are correct about the structure declaration given below?

      struct Book
      {
          private String name; 
          protected int totalpages; 
          public Single price; 
          public void Showdata()
          {
              Console.WriteLine(name + " " + totalpages + " " + price);
          } 
          Book()
          {
              name = " "; 
              totalpages = 0;
              price = 0.0f; 
          } 
      } 
      Book b = new Book();
      1. We cannot declare the access modifier of totalpages as protected.
      2. We cannot declare the access modifier of name as private.
      3. We cannot define a zero-argument constructor inside a structure.
      4. We cannot declare the access modifier of price as public.
      5. We can define a Showdata() method inside a structure.

          .age = 25;
          .sal = 5500; 
      }
    • C.
      With emp e
      {
          .name = "Amol";
          .age = 25;
          .sal = 5500; 
      }
    • D.
      e -> name = "Amol"; 
      e -> age = 25;
      e -> sal = 5500;
