用C语言定义包含图书信息的顺序表和链表

您好！以下是使用C语言定义包含图书信息的顺序表和链表的示例代码：

1. 顺序表

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

#define MAX_SIZE 100    // 定义最大容量

typedef struct book {
    char name[30];
    char author[20];
    float price;
} Book;

typedef struct sqList {
    Book data[MAX_SIZE];
    int length;
} SqList;

int main() {
    SqList L;
    L.length = 0;

    // 插入元素
    Book book1 = {"The Catcher in the Rye", "J.D. Salinger", 25.5};
    L.data[L.length++] = book1;

    Book book2 = {"To Kill a Mockingbird", "Harper Lee", 30.0};
    L.data[L.length++] = book2;

    // 遍历输出
    for (int i = 0; i < L.length; i++) {
        printf("书名：%s\n作者：%s\n价格：%.2f\n\n", L.data[i].name, L.data[i].author, L.data[i].price);
    }

    return 0;
}

2. 链表

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

typedef struct book {
    char name[30];
    char author[20];
    float price;
    struct book *next;
} Book;

typedef struct linkedList {
    Book *head;
    int length;
} LinkedList;

int main() {
    LinkedList L;
    L.head = NULL;
    L.length = 0;

    // 插入元素
    Book *book1 = (Book *)malloc(sizeof(Book));
    strcpy(book1->name, "The Catcher in the Rye");
    strcpy(book1->author, "J.D. Salinger");
    book1->price = 25.5;
    book1->next = NULL;

    L.head = book1;
    L.length++;

    Book *book2 = (Book *)malloc(sizeof(Book));
    strcpy(book2->name, "To Kill a Mockingbird");
    strcpy(book2->author, "Harper Lee");
    book2->price = 30.0;
    book2->next = NULL;

    book1->next = book2;
    L.length++;

    // 遍历输出
    Book *p = L.head;
    while (p != NULL) {
        printf("书名：%s\n作者：%s\n价格：%.2f\n\n", p->name, p->author, p->price);
        p = p->next;
    }

    // 释放内存
    p = L.head;
    while (p != NULL) {
        Book *q = p;
        p = p->next;
        free(q);
    }

    return 0;
}

希望这个例子能帮到您！
