C Sharp

Examination & Test - Lập trình C# - Lập trình C Sharp

1. Tạo 1 lớp giao diện IInfor chứa hàm showInfor

2. Tạo lớp đối tượng People gồm các thuộc tính tên, tuổi, địa chỉ kế thừa từ lớp IInfor

- Tạo hàm input

Tạo lớp Car gồm các thuộc tính tên và màu -> kế thừa từ lớp IInfor

- Tạo hàm input

Viết code cho các lớp trên.

3. Trọng phương thức main của lớp Test tạo 2 đối tượng People và Car. 

- tạo phương thức như sau.

public static void showInfor(List<IInfor> a) -> hàm này hiển thị thông tin tất cả đối tượng.

Viết chương trình và sử dụng hàm showInfor trong phương thức main.
