Viết hàm nhập và hạm hiển thị tất cả các thuộc tính của lớp đối tượng

- Sách gồm các thuộc tính : bút danh tác giả, nhà xuất bản, tên sách, (Tự thêm các thuộc tính cần thiết của sách vào)

Viết hàm nhập và hàm hiển thị 

Yêu cầu:

- Tạo các class object tương ứng

- Tạo getter/setter

- Tạo hàm tạo cho class object

- Viết các hàm nhập và hiển thị cho từng class object

- Viết đoạn chương trình khai báo 3 đối tượng nhà xuất bản, tác giả, sách.
