帮忙具体解释下这个程序哦，明天考试哦，急
#include<stdio.h>
#include<string.h>
#include<malloc.h>
#define LEN sizeof(struct score)
struct  score
{char num[4];
 int score;
struct score *next;
};
struct score *creat(void)
{struct score *head;
struct score *p1,*p2;
int i ;
for(i=0;i<2;i++)
{ p1 =(struct score *) malloc(LEN);
if(i==0) head=p2=p1;
else
{p2->next=p1;
p2=p1;}
scanf("%s  %d",p1->num,&p1->score);
}
p1->next=NULL;
return (head);
}

struct score* insert (struct score *head, struct score *nscore)
{
 struct score *p0,*p1,*p2;
 p1=head;
 p0=nscore;
 if(head==NULL)
   {head=p0;p0->next=NULL;}
 else
   {while(strcmp(p0->num,p1->num)>0&&(p1->next!=NULL))
     {p2=p1;
      p1=p1->next;}
      if(strcmp(p0->num,p1->num)<0)
        {if(head==p1)head=p0;
        else p2->next=p0;
        p0->next=p1;}
      else
    {p1->next=p0;
    p0->next=NULL;
}
    } return head
}
void main()
{
struct score *p1,*p2,*head;
head=creat();
printf("please input a shuju");
p1 =(struct score *) malloc(LEN);
scanf("%s  %d",p1->num,&p1->score);
insert(head,p1);
p2=head;
while(p2)
{printf(  "     %s    ,    %d\n",p2->num,p2->score);p2=p2->next;}
}

大虾们帮帮忙哦

链表建立与插入

如果这个程序你现在还看不懂的话,我建议你准备好作弊工具或者重修费

printf("please input a shuju");
汗一下这句中英结合的提示语句.....

能说详细点吗？

郁闷哦

平时不用功，临阵抱佛脚。
好好看看书。
