着里面有好多错误
帮忙看看 怎么改
#include"stdio.h"
#include"stdlib.h"
struct slist
{
int data;
struct slist *next;
};
typedef struct slist SLIST;
SLIST *creat() ;
void print(SLIST *head) ;

main()
{
SLIST *head;
head=creat();
print(head);
}
SLIST *creat()
{
int c;
SLIST *h,*s,*r;
h=(SLIST*)malloc(sizeof(SLIST));
r=h;
scanf("%d",&c);
while(c!=-1)
{
s=(SLIST*)malloc(sizeof(SLIST));
s.data=c;
r.next=s;
r=s;
scanf("%d",&c);
}
r.next='\0';
return h;
}
void print(SLIST *head)
{
SLIST *p;
p=head.next;
if(p=='\0')
printf("连表为空\n");
else{
printf("head");
double{
printf("->%d",p.data);
p=p.next;
}
while(p!='\0');
printf("->end\n");
}
}

错的是概念上的问题
指针类型应该用"->" 来操作的,给你改完了

#include\"stdio.h\"
#include\"stdlib.h\"
#include\"malloc.h\"
struct slist
{
    int data;
    struct slist *next;
};
typedef struct slist SLIST;
SLIST *creat();
void print(SLIST *head);

int main()//养成习惯便于以后象C++过渡
{
    SLIST *head;
    head=creat();
    print(head);
    return 0;
}
SLIST *creat()
{
    int c;
    SLIST *h,*s,*r;
    h=(SLIST*)malloc(sizeof(SLIST));
    h->next=NULL;//链表中尽量用NULL表示结尾 或者在程序前宏定义#define null 0
    r=h;
    scanf(\"%d\",&c);
    while(c!=-1)
    {
        s=(SLIST*)malloc(sizeof(SLIST));
        s->data=c;//指针类型注意\"->\"
        s->next=r->next;
        r->next=s;
        r=s;
        scanf(\"%d\",&c);
    }
    return h;
}
void print(SLIST *head)
{
    SLIST *p,*q;
    p=head->next;
    if(p==NULL)
    printf(\"连表为空\n\");
    while(p!=NULL)
 {
 printf(\"%d->\",p->data);
 q=p;
 p=p->next;
 free(q);//输出后记得释放节点,节约内存
 }
 printf(\"NULL\n\");
}

恩
