我只是想让更多人  想进来看看是什么东西

周末没上这个论坛。周一看到的，写了代码，没调好就有同学找我出去了，然后没完成。
今天完成了，也通过，不过你已经知道怎么做了。所以就这样了。
但是还是我的代码贴出来了，毕竟是我的成果：
#include <stdio.h>
#include <stdlib.h>
#include <string.h>


typedef struct node

    int StuNum;
    char StuName[20];

    struct node *pnext;
}node_t;

node_t *pcurr = NULL;

//输出结构体里的成员变量值
int PrintData(node_t *tmp)                        //参数是指针

    node_t *tmp1 = tmp;

完了点

但还是谢谢你

呵呵，你看答你的帖子的都得写那么多代码，版主一般都很忙的～～

其实我觉得你问问怎么读文件就行了。如果从文件里解析出来之后，你还写不进链表，那就是你自己下的功夫不够了～～
