感謝各位的回答。我後來還是用了strtok來做。大概把我想要的樣子都弄出來了。感想：1. 程式語言很多東西不自己實際演練過還真的不會了解。 2. pointer真的是很好玩的東西，有它在我就不會想去玩Java了。程式碼更新在此： https://gist.github.com/gnitnaw/11ad7e7a98e4ebc8601f #include <stdio.h> #include <stdlib.h> #include <string.h> #define SIZE 256 #define NITEM 15 int getData(char* line, char** t); void outputResult(FILE *fout, char** title, char** t, int N); int main(void) { char s; int i, j, N; char **t = (char**)malloc(sizeof(char*)*NITEM); char **title = (char**)malloc(sizeof(char*)*NITEM); char* line = (char*)malloc(sizeof(char)*SIZE); FILE *fp = fopen("Example_table.txt", "r"); FILE *fout = fopen("output.txt", "a"); if (!fp) { perror("Error!
