Sử dụng if else và else if Tạo một Hệ thống chấm điểm đơn giản trong PHP

Cho một mảng số nguyên điểm, bao gồm các điểm được ghi bởi một học sinh (trên 100 điểm) trong các môn học khác nhau, nhiệm vụ là gán điểm cho học sinh. Điểm được tính bằng cách lấy tỷ lệ phần trăm số điểm mà học sinh ghi được. Tỷ lệ phần trăm được tính như.  

Điểm được chỉ định theo các quy tắc sau.
 

Ví dụ.
 

Đầu vào. điểm = { 25, 65, 46, 98, 78, 65 } 
Đầu ra. C
Đầu vào. điểm = { 95, 88, 98, 93, 92, 96 } 
Đầu ra. Đ
 

Khuyến khích. Vui lòng thử cách tiếp cận của bạn trên {IDE} trước, trước khi chuyển sang giải pháp

Cách tiếp cận.
 

• Khởi tạo một biến để tính tổng tất cả các điểm mà học sinh ghi được, tổng bằng 0.
   
• Khởi tạo một biến để lưu điểm của học sinh, điểm ‘F’.
   
• Đầu tiên, chúng tôi duyệt qua mảng điểm và tìm tổng điểm mà học sinh ghi được.
   
• Sau đó, chúng tôi áp dụng công thức được mô tả ở trên để tính tỷ lệ phần trăm.
   
• Sau đó, chúng ta tạo một cấu trúc if lồng nhau để gán điểm thích hợp cho học sinh.
   

Để biết thêm về việc ra quyết định và các loại cấu trúc ra quyết định khác nhau, hãy tham khảo Ra quyết định trong Java.
Dưới đây là cách triển khai của phương pháp trên.
