使用来链表实现图书信息的录入，排序，插入，查找，删除，修改，统计，浏览

以下是使用链表实现图书信息管理的示例代码：

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

// 定义图书信息结构体
typedef struct Book {
    char name[50]; // 书名
    char author[20]; // 作者
    char publisher[30]; // 出版社
    int year; // 出版年份
    float price; // 价格
    struct Book *next; // 指向下一本书的指针
} Book;

// 定义链表头指针
Book *head = NULL;

// 函数声明
void addBook();
void sortBooks();
void insertBook();
void searchBook();
void deleteBook();
void modifyBook();
void countBooks();
void browseBooks();

int main() {
    int choice;
    while (1) {
        printf("\n图书信息管理系统\n");
        printf("1. 录入图书信息\n");
        printf("2. 排序图书信息\n");
        printf("3. 插入图书信息\n");
        printf("4. 查找图书信息\n");
        printf("5. 删除图书信息\n");
        printf("6. 修改图书信息\n");
        printf("7. 统计图书信息\n");
        printf("8. 浏览图书信息\n");
        printf("0. 退出系统\n");
        printf("请选择操作：");
        scanf("%d", &choice);
        switch (choice) {
            case 1:
                addBook();
