单链表头插法出错

单链表头插法报错 急
目的是输入什么再倒叙输出什么(因为是头插)  现在报错的离谱   求助

#include<stdio.h>
#include<malloc.h>
#include<conio.h>
typedef struct node{
int data;
struct node *next;
}NODE;
NODE *HeadCreate(){
NODE *head, *p;               
char a='+';
int datas=0;
head = (NODE *)malloc(sizeof(NODE));
head->next=NULL;
printf("请输入数据,结尾以‘*’结束:");
while (a != '*'){
p = (NODE *)malloc(sizeof(NODE));
scanf("&d",&datas);
p->data = datas;
p->next = head;
head = p;
a = getchar();
}
return head;
}
void main(){
NODE *a;
a = HeadCreate();
printf("输出结果:");
while (a != NULL){
printf("%d ",a->data);
a = a->next;
}
getch();
}

单链表头插法出错

------解决思路----------------------
楼主,你这写得很乱,而且存在大量的内存泄露。还有楼主,main函数标准写法是带返回值的,以及格式输入是%d不是&d

正确代码:
#include<stdio.h>
#include<malloc.h>
#include<conio.h>
typedef struct node{
    int data;
    struct node *next;
}NODE;
NODE *HeadCreate(){
    NODE *head, *p;               
    char a='+';
    int datas=0;
    head = (NODE *)malloc(sizeof(NODE));
    head->next=NULL;
    printf("请输入数据,结尾以‘*’结束:");
    while (a != '*'){
        p = (NODE *)malloc(sizeof(NODE));
        scanf("%d",&datas);
        p->data = datas;
        p->next = head->next;
        head->next = p;
        a = getchar();
    }
    return head;
}
int main(){
    NODE *a;
    a = HeadCreate();
    printf("输出结果:");
a = a->next;
    while (a != NULL){
        printf("%d ",a->data);
        a = a->next;
    }
    getch();
return 0;
}
