Sau khi đã làm xong và nộp thầy... chúng ta có thể post thành quả lên đây cho ae nào phải thi lại môn này theo dõi nhé

Đầu tiên là tui với đề 2 (sau khi pó tay với đề 1 - Thẻ ATM, nếu có thắc mắc j về đề 1 này, PM mod Ainq_c00498)

Đề 2 là làm thế nào để lập 1 danh sách quản lý đĩa CD (cái này là test thôi, ae xem có j fix lại cho chuẩn nhé)
