C语言链表初始化错误

Question

C语言链表问题

#include<stdio.h>
#include<stdlib.h>

typedef struct
{
    int num;
    char name[20];
}People;

typedef People datatype;

typedef struct node
{
    char name[20];
    datatype data;    
    struct node *next;
}LinkList;
//头插法建表
void CreateListF(LinkList *&head,datatype a[],int m,int n) 
{
    LinkList *p;int i;
    head =(LinkList *)malloc(sizeof(LinkList));
    head ->next=NULL;
    for(i=m;i<n;i++)
    {    p=(LinkList *)malloc(sizeof(LinkList));
        p->data=a[i];
        p->next= head ->next;
        head ->next=p;
    }
}
//初始化线性表
LinkList *InitList() 
{
    LinkList *head=(LinkList *)malloc(sizeof(LinkList));
    head->next=NULL;
    return head;
}
//输出线性表
void print(LinkList *head) 
{
    LinkList *p=head->next;
    while(p!=NULL)
    {     
        printf("%c",p->data);
        p=p->next; 
    }
}
//主程序 
int main(){

    datatype People[12] ={
    {101401,"雷震子"}, 
    {100032,"姜子牙"},
    {101674,"哪吒"},
    {101982,"申公豹"},
    {107431,"九尾狐"},
    {100001,"天尊"},
    {101009,"太乙"},
    {101321,"杨戬"},
    {101567,"黄飞虎"},
    {108160,"纣王"},
    {102456,"李靖"},
    {102245,"土行孙"},
    };
    
    LinkList *L1,*L2,*L3;
    L1=InitList();
    L2=InitList();
    L3=InitList();
    CreateListF(L1,People,0,5);
    CreateListF(L2,People,5,8);
    CreateListF(L3,People,8,12);    
    print(L1);
    print(L2);
    print(L3);
}

输出结果：p..
(12个p)
