问题相关代码，请勿粘贴截图

#include <iostream>
#include <stdlib.h>
typedef int  ElemType;
typedef struct Node
{
    ElemType ISBN;
    char name[10];
    char writer[10];
    char location[10];
    float price;
    struct Node*next;
}book;
void InitList(book *&L)
{
    L=(book *)malloc(sizeof(book));
    if(L==NULL)
    {
        printf("内存分配失败!!\n");
        exit(0);
    }
    L->next==NULL;
}
void creatList(book *&L,ElemType n)//n为要插入图书的数量 
{
    int i;
    book *s,*r;
    r=L;//r为为指针;
    for(i=0;i<n;i++)
    {
        s=(book *)malloc(sizeof(book));
        printf("请输入ISBN号:\n");
        scanf("%d",&(s->ISBN));
        printf("请输入书名:\n");
        scanf("%s",s->name);
        printf("请输入出版社:\n");
        scanf("%s",s->location);
        printf("请输入作者名:\n");
        scanf("%s",s->name);
        printf("请输入价格:\n");
        scanf("%f",&s->price);
        r->next=s;
        r=s;
    }
    r->next=NULL; 
}
void printfbooklist(book *&L)
{
    book *pmove=L->next;
    printf("ISBN    出版社   书名    作者名   价格 \n");
    while(pmove)
    {
        printf("%5d %s %s %s  %5f\n",pmove->ISBN,pmove->location,pmove->name,pmove->writer,pmove->price);
        pmove=pmove->next;
    }
}
int main()
{
    int k,j;
    book *L;
    InitList(L);
    printf("请输入要插入的图书数量:\n");
    scanf("%d",&k);
    creatList(L,k);
    printfbooklist(L);
}
