C语言:结构体与数组

#include <stdio.h>
struct book{
        char title[];
        char author[];
        int price;
};
 
int arr[] = {,,,,,,,,,};
 
int main(){
        struct book *ps1;
        struct book c = {
                "PHP最佳实践",
                "jimmy",
                ,
        };
        printf("%p\n",c);
        printf("%p\n",&c.title);
        //1 结构体指针的赋值
        ps1 = &c;
        //数组指针的赋值
        int *ps2;
        ps2 = arr;
 
        //结构体数组
        struct book d[];
        struct book *ps3;
        ps3 = &d[];
 
        //二维数组
        int arr2[][] = {,,,,,,,};
        int (*ps4)[];
        ps4 = arr2;
        printf("%d,%d\n",*(*ps4+),*(*(ps4+)+));
}
