Viết chương trình quản lý sinh viên + delegate & event trong C# - Lập Trình C# - Lập Trình C Sharp BT1523

Viết chương trình quản lý thông tin sinh viên.

Thông tin sinh viên gồm các thuộc tính sau : tên, tuổi, mã sinh viên, địa chỉ, email, sđt, mã phụ huynh -> Viết hàm nhập và hàm hiển thị

Thông tin phụ huynh gồm các thuộc tính : tên, địa chỉ, sđt, mã phụ huynh -> Mỗi sinh viên sẽ được liên kết vs một phụ huynh -> Viết hàm nhập và hàm hiển thị

(Chú ý 1 phụ huynh có thể được liên kết vs nhiều sv)

Yêu cầu tạo menu chương trình

1. Nhập thông tin N phụ huynh

2. Nhập thông tin M sinh viên

3. Nhập tên phu huynh -> In ra thông tin các sinh viên được tham chiếu bởi phụ huynh này

4. Nhập thông tinh sv -> In ra thông tin tra cứu phụ huynh

5. Tạo delegate OnAddressPrint và sự kiện EventAddressPrint -> Thực hiện in thông tin sinh viên theo địa chỉ nhập vào.
