Chắc là báo lỗi thiếu thư viện
#include<conio.h>đúng không? Thư viện này cũ rồi, code này cũng cũ lắm rồiNó báo lỗi thư viện # < iomanip> ạ, em dùng dev-c++
Viết lại chính xác là
xem có lỗi không?
Giờ thì nó báo lỗi tùm lùm luôn. Em xem lại vậy
Đã xem và phát hiện như sau:
Cảm ơn bạn @david15894 , mình đã sửa hehe
