C Sharp
Bài 2: Chương trình quản lý sản phẩm - Product - Lập Trình C# - Lập Trình C Sharp
Tạo class Product gồm các thuộc tính:
- Tên hàng hóa
- Nhà sản xuất
- Giá bán
+ Tạo 2 constructor cho lớp này.
+ Cài đặt hàm nhập và hiển thị.
Tạo class ProductMenu, khai báo hàm main và tạo menu sau:
1. Nhập thông tin cho n sản phẩm
2. Hiển thị thông tin vừa nhập
3. Sắp xếp thông tin giảm dần theo giá và hiển thị
4. Thoát.
