基于顺序存储结构的图书信息表的逆序存储代码

下面是基于顺序存储结构的图书信息表的逆序存储代码：

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

#define MAXSIZE 100

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

typedef struct {
    Book data[MAXSIZE];
    int length;
} BookList;

void reverse(BookList *L) {
    int i;
    Book temp;
    for (i = 0; i < L->length / 2; i++) {
        temp = L->data[i];
        L->data[i] = L->data[L->length - i - 1];
        L->data[L->length - i - 1] = temp;
    }
}

int main() {
    BookList L;
    int i;
    L.length = 5;
    strcpy(L.data[0].name, "C Programming");
    strcpy(L.data[0].author, "Dennis Ritchie");
    strcpy(L.data[0].publisher, "Prentice Hall");
    L.data[0].price = 22.99;
    strcpy(L.data[1].name, "The C Programming Language");
    strcpy(L.data[1].author, "Brian Kernighan");
    strcpy(L.data[1].publisher, "Prentice Hall");
    L.data[1].price = 31.55;
    strcpy(L.data[2].name, "Head First C");
    strcpy(L.data[2].author, "David Griffiths");
    strcpy(L.data[2].publisher, "O'Reilly Media");
    L.data[2].price = 29.99;
    strcpy(L.data[3].name, "C Primer Plus");
    strcpy(L.data[3].author, "Stephen Prata");
    strcpy(L.data[3].publisher, "Sams Publishing");
    L.data[3].price = 39.99;
    strcpy(L.data[4].name, "Effective C");
    strcpy(L.data[4].author, "Scott Meyers");
    strcpy(L.data[4].publisher, "Addison-Wesley Professional");
    L.data[4].price = 49.99;

    printf("Original book list:\n");
    for (i = 0; i < L.length; i++) {
        printf("%s\t%s\t%s\t%.2f\n", L.data[i].name, L.data[i].author, L.data[i].publisher, L.data[i].price);
    }

    reverse(&L);

    printf("Reversed book list:\n");
    for (i = 0; i < L.length; i++) {
        printf("%s\t%s\t%s\t%.2f\n", L.data[i].name, L.data[i].author, L.data[i].publisher, L.data[i].price);
    }

    return 0;
}
