mình có đoạn code như sau
các bác cho hỏi là unsigned char code code_Tab[97][6]
là khai báo ra sao vậy vì thường mình thấy khai báo mảng phía sau tên mảng là [xx] còn ở đây là [xx] [yy].?????
và 1 cái nũa là khai báo
unsigned char *String_input ="ngay moi tot lanh van su nhu y ";
*string_input là cấu trúc khai báo tên đại diện của 1 chuỗi ký tự ha?(có *phía trước nữa -lạ quá???)
vậy muốn tạo font tiếng việt thì mình phải khai báo như thế nào để trình keilC hiều???/ mong các bác giải đáp giúp e

vậy muốn tạo font tiếng việt thì mình phải khai báo như thế nào để trình keilC hiều???/ mong các bác giải đáp giúp e
