关于c语言结构的简单问题，这个程序为什么不能不能通过呢？

Question

#include<stdio.h>
struct books
{
    int bno;
    char bname[20],field[20],publisher[20],author[10];
    float price;
};
int mian()
{
    struct books book[3]={
    {101,"kk","cc","fj","fs",29},{102,"hg","ja","jkg","gia",30},{103,"saj","ajf","khg","jgs",24}
    }; 
    printf("%s\n",book[1].bname);
    printf("%s\n",(*(book+1)).bname);
    printf("%s",(book+1)->bname);
    return 0;
}

Answer 1

int mian()错了，改成main 不是mian
