c语言链表编程有关问题，实在找不到bug，求帮忙

c语言链表编程问题，实在找不到bug，求帮忙
我编写了一个链表，想用来存储学生信息，使用的头插法。运行结果很奇怪，编译没问题，但就是找不到bug，代码如

下：
#include <stdio.h>
#include <string.h>

typedef struct Info
{
int num;
char name[10];
int age;
char sex;
struct Info *next;
}StuInfo;
typedef StuInfo *InfoList;

InfoList Creater();

void main()
{
InfoList newlist = Creater();
}

InfoList Creater()
{
InfoList head;
StuInfo *p, *tail;

head = NULL;
tail = NULL;

p = (InfoList)malloc(sizeof(StuInfo));
if (!p)
{
printf("No memory left.");
return head;
}
printf("Num: ");
scanf("%d",*(p->num));

while(p->num[0])
{
printf("Name: ");
scanf("%s",&(p->name));
printf("Age: ");
scanf("%d",&(p->age));
printf("Sex: ");
scanf("%c",&(p->sex));
if (head == NULL)
head = p;
else
tail->next = p;
tail = p;

p = (InfoList)malloc(sizeof(StuInfo));
if (!p)
{
printf("No memory left");
goto endwhile;
}
printf("Num: ");
scanf("%d",*(p->num));
}

endwhile:if (tail)
tail->next = NULL;

return (head);
}

希望有人能够指点迷津，小弟将不胜感激。

[解决办法]

C/C++ code
