建立储存20个学生信息的单链表，我的程序如下：

/* Note:Your choice is C IDE */
#include "stdio.h"
#include <malloc.h>

struct  person{
     long  num;
    char name[20];
     char sex;
     int age;
     long tel;
}student;

typedef struct stu{
    struct person  student;
    struct stu  *next;
}linklist;

linklist  *creatlist()
{
    int i;
    struct person x;
    linklist  *head,*p,*r;
    p=(linklist*)malloc(sizeof(linklist));
    head=p;
    p->next=NULL;
    r=p;
    for(i=0;i<=20;i++)
    {
        scanf("%ld%c%c%d%ld",&x.num,&x.name[i],&x.sex,&x.age,&x.tel);
        p=(linklist*)malloc(sizeof(linklist));
        p->student.num=x.num;
        p->student.name[i]=x.name[i];
        p->student.sex=x.sex;
        p->student.age=x.age;
        p->student.tel=x.tel;
        p->next=NULL;
        r->next=p;
        r=r->next;
    }
    return(head);
    }
void main()
{
    int i;
     linklist *stdhead;
     for(i=0;i<=20;i++)
    {stdhead=creatlist();
    
    printf("%ld,%c,%c,%d,%ld\n",stdhead->num,stdhead->name[i],stdhead->sex,stdhead->age,stdhead->tel);
    }
}
请高手指正其中的错误，多谢多谢！

void main()
{
    int i;
     linklist *stdhead;
     for(i=0;i<=20;i++)
    {
         stdhead=creatlist();
   
    printf("%ld,%c,%c,%d,%ld\n",stdhead->student.num,stdhead->student.name[i],\
        stdhead->student.sex,stdhead->student.age,stdhead->student.tel);
    }
}

vfdff你还没给我改完啊，这样依旧运行不成功啊,你再给看看吧，拜托啦……

        printf("please enter the num");
        scanf("%ld",&p->student.num);
        printf("please enter the name");

    }

请各路高手帮忙改一下，问题不是很大了，可就是不知道出在哪儿!!!帮帮忙吧，各路高手……
多谢，多谢……

编写程序时,加上必要的注释是很重要的.我在帮你调试程序时,光为了理解各个字符的意义就花了很长的时间!

楼上正解
