给定程序中已建立一个带有头结点的单向链表，链表中的各结点按结点数据域中的数据从小到大顺序链接。函数fun的功能是：把形参x的值放入一个新结点并插入到链表中，插入后各结点仍保持从小到大顺序排列。
请在程序的下划线处填入正确的内容并把下划线删除，使程序得出正确的结果。
注意：源程序存放在考生文件夹下的BLANK1.C中。
不得增行或删行，也不得更改程序的结构！

谁会就帮帮我啊..

OK没有问题了:
#include <stdio.h>
#include <stdlib.h>
#define N 8
typedef struct list
{ int data;
struct list *next;
} SLIST;
void fun( SLIST *h, int x)
{ SLIST *p, *q, *s;
s=(SLIST *)malloc(sizeof(SLIST));
/**********found**********/
s->data=x;
q=h;
p=h->next;
while(p!=NULL && x>p->data) {
/**********found**********/
q=s;
p=p->next;
}
s->next=p;
/**********found**********/
q->next=s;
}
SLIST *creatlist(int *a)
{ SLIST *h,*p,*q;
int i;
h=p=(SLIST *)malloc(sizeof(SLIST));
for(i=0; i<N; i++)
{ q=(SLIST *)malloc(sizeof(SLIST));
q->data=a[i]; p->next=q; p=q;
}
p->next=0;
return h;
}
void outlist(SLIST *h)
{ SLIST *p;
p=h->next;
if (p==NULL) printf("\nThe list is NULL!\n");
else
{ printf("\nHead");
do { printf("->%d",p->data); p=p->next; } while(p!=NULL);
printf("->End\n");
}
}
int main(void)
{ SLIST *head; int x;
int a[N]={11,12,15,18,19,22,25,29};
head=creatlist(a);
printf("\nThe list before inserting:\n"); outlist(head);
printf("\nEnter a number : "); scanf("%d",&x);
fun(head,x);
printf("\nThe list after inserting:\n"); outlist(head);
return 0;
}

谢谢.
