ko ai giúp mình rùi .bun quá

[tienhuypro]

Đưa cả chương trình này lên thì còn ai muốn giúp cái chi nữa

[chung1608]

mạch đâu ko port làm sao biết code chạy ra sao

To thanhvan90,

Ai cũng muốn giúp bạn cả nhưng nếu bạn là họ thì bạn sẽ giúp thế nào với câu hỏi này. Muốn người khác giúp được mình thì phải cung cấp đầy đủ thông tin để họ hiểu cái mình đang làm, cái mình đang gặp khó khăn một cách nhanh nhất và dễ hiểu nhất. Bạn nên đưa sơ đồ nguyên lý lên, mô tả ngắn gọn cách hoạt động của sơ đồ nguyên lý theo ý hiểu của bạn. Phần mềm thì đưa lưu đồ lên hoặc ít nhất là mô tả giải thuật của bạn để người khác đánh giá xem nó chưa ổn ở chỗ nào. Không ai có thời gian để ngồi dò từng dòng code mà sửa giúp bạn đâu.

Bạn thử mô tả lại bài toán đi rồi post lên để anh em giúp.

Thân.
