如何从FILE中读取一行，直到看到换行符？

Question

我正在从文件读取数据到我的列表。每个数据都逐行写入我的txt。我使用fgets读取包含字符的行，不幸的是，它也读取'\ n'。我需要阅读一些内容，直到在代码中看到“ \ n”为止。我使用fscanf（“ [^ \ n] c”）这样的东西，它不起作用。我该怎么办？（对不起我的英语不好。我希望自己能解释一下）

    char author[50];
    int book_id;

    double price;
    int shelf_no;
    struct library* next;

    node* iter;

    FILE* fptr = fopen("data.txt", "r");
    fseek(fptr, 0, SEEK_END);


    if (ftell(fptr) == 0)
    {
        printf("*");
        fclose(fptr);
        return NULL;
    }


    else {


        fseek(fptr, 0, SEEK_SET);

        head = (node*)calloc(1,sizeof(node));
        head->next = NULL;
        iter = head;
        head->book_id = -1;


        while (feof(fptr) != 1) {

            fgets(iter->catagory,50,fptr);
            fgets(iter->book_name, 50, fptr);
            fgets(iter->author, 50, fptr);




            fscanf(fptr, "%d", &iter->book_id);
            fscanf(fptr, "%d", &iter->quantity);
            fscanf(fptr, "%lf",&iter->price);

        }
        return head;
        fclose(fptr);


    }

}

void view_book(node* root) {

    printf("############################# BOOK LIST #############################\n");
    printf("Category\tID\tBook Name\tAuthor\tQTY\tPRICE\tShelf No\n");
    node* move;

}

Answer 1

fscanf(fptr, "%[^\n]%*c", &iter->catagory);

这是解决方案
