用c++语言编写一个完整代码 要求在主函数中，可以创建一个指向 Book 类的指针数组，然后动态地创建 Book 类的对象和 EBook 类的对象，将这些对象存储到指针数组中。然后，可以通过循环来调用每个对象的 print() 函数，实现多态输出。编程不要中断

以下是在 C 语言中使用多态的一个示例代码：

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

// 定义基类 Book
typedef struct Book {
    char* title;
    char* author;
    int pageCount;
    void (*print)(struct Book*); // 函数指针，指向输出函数
} Book;

// 定义派生类 EBook
typedef struct EBook {
    Book book;
    char* fileSize;
} EBook;

// 定义基类的输出函数
void book_print(Book* book) {
    printf("Title: %s\n", book->title);
    printf("Author: %s\n", book->author);
    printf("Page count: %d\n", book->pageCount);
}

// 定义派生类的输出函数
void ebook_print(Book* book) {
    EBook* ebook = (EBook*)book; // 将指向基类的指针转换为指向派生类的指针
    printf("Title: %s\n", ebook->book.title);
    printf("Author: %s\n", ebook->book.author);
    printf("Page count: %d\n", ebook->book.pageCount);
    printf("File size: %s\n", ebook->fileSize);
}

int main() {
    // 创建指向 Book 类的指针数组
    Book** books = (Book**)malloc(sizeof(Book*) * 2);

    // 动态创建 Book 类的对象
    Book* book1 = (Book*)malloc(sizeof(Book));
    book1->title = "Book 1";
    book1->author = "Author 1";
    book1->pageCount = 100;
    book1->print = book_print; // 设置函数指针
    books[0] = book1;

    // 动态创建 EBook 类的对象
    EBook* ebook1 = (EBook*)malloc(sizeof(EBook));
    ebook1->book.title = "EBook 1";
    ebook1->book.author = "Author 1";
    ebook1->book.pageCount = 50;
    ebook1->book.print = ebook_print; // 设置函数指针
    ebook1->fileSize = "1MB";
    books[1] = (Book*)ebook1;

    // 通过循环调用每
