C语言实现利用链表实现一个简单的图书信息管理系统

好的，这是一个简单的图书信息管理系统，使用链表实现：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

struct book {
    char title[50];
    char author[50];
    int pages;
    struct book *next;
};

void add_book(struct book **library, char title[], char author[], int pages) {
    struct book *new_book = (struct book*) malloc(sizeof(struct book));
    strcpy(new_book->title, title);
    strcpy(new_book->author, author);
    new_book->pages = pages;
    new_book->next = NULL;

    if (*library == NULL) {
        *library = new_book;
    } else {
        struct book *current_book = *library;
        while (current_book->next != NULL) {
            current_book = current_book->next;
        }
        current_book->next = new_book;
    }
}

void print_library(struct book *library) {
    struct book *current_book = library;
    while (current_book != NULL) {
        printf("Title: %s\n", current_book->title);
        printf("Author: %s\n", current_book->author);
        printf("Pages: %d\n\n", current_book->pages);
        current_book = current_book->next;
    }
}

int main() {
    struct book *library = NULL;

    add_book(&library, "The Great Gatsby", "F. Scott Fitzgerald", 180);
    add_book(&library, "To Kill a Mockingbird", "Harper Lee", 281);
    add_book(&library, "1984", "George Orwell", 328);

    print_library(library);

    return 0;
}

这个程序定义了一个 `book` 结构体来表示每一本书，包括标题、作者和页数。然后定义了一个 `add_book` 函数来添加一本新书到图书馆链表中，以及一个 `print_library` 函数来打印整个图书馆。在 `main` 函数中，我们添加了三本书到图书馆，然后打印整个图书馆。
