在结构数组中分配结构数据？

Question

Header file book_info struct

struct book_info {
         char title[50];
         char author[40];
         unsigned int year_published;
     };

typedef book_info;
book_info books[20];

void init_heap() {
    head = 0;
    for(int i = 0; i < 19; i++) {
            books[i].year_published = i+1;
        }
    books[20].year_published = 10000;
}

Trying to make an array of book_info structs, and then assign the year published of each struct to a number when initializing. Not sure exactly what the problem is?

Answer 1

Instead of

typedef book_info;

you need

typedef struct book_info book_info;

Answer 2

you can solve this problem by two ways.

1. typedef struct book_info book_info;

2.

struct book_info{
//...
    }books[20];
