Bài này hơi dài, tuy nhiên có những hàm chạy hay, các bạn tham khảo và viết lại code cho mình, có rảnh thì up bài do mình làm lên cho mọi người tham khảo nha. Nếu lưu lại nhớ đặt đuôi là .c nếu bạn muốn đuôi .cpp thì bạn thêm thư viện #include "ctype.h"
- Code:
#include "stdio.h"
#include "string.h"
#define MAX 100
