我正在尝试创建一个程序,将每个具有书名的行从文件转换为字符数组,因为我需要稍后调用每本书,所以书[1],书[2]等等. ,我无法弄清楚如何使用我的结构创建数组.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stddef.h>
#define Num_Book 9

typedef struct book {
  char *book_name;
  size_t length;
  ssize_t title;
}BOOK;

int main(int argc, char* argv[])
{
  BOOK *Book;
  Book = (BOOK *) malloc (sizeof(BOOK));

  (*Book).book_name = NULL;
  (*Book).length = 0;
  char title_arr[Num_Book][50]; 
  //this is the array that I tried creating, 
  //but it kept giving me warnings when I tried to compile

//opening my file
FILE *f_books;
f_books = fopen("books.txt", "r");

if (f_books == NULL)
{ …
