C++對動態(tài)字符的二進(jìn)制讀取

我的代碼有問題，我不知道問題的確切原因。

Source.cpp

#include "class.h"

int main()
{
    Book book1("At Mountain of Madness", "H.P Lovecraft", 1936);
    book1.binaryFileWrite();
    book1.binaryFileRead();

    Book book2("Danwych's horror", "H.P Lovecraft", 1929);
    book2.binaryFileWrite();
    book2.binaryFileRead();

    
}

#ifndef BOOK_BINARY_LIBRARY
#define BOOK_BINARY_LIBRARY

#include <cstring>
#include <iostream>
#include <fstream>
#include <string>

class Book
{
public:
    Book()
        : _year(0)
    {
        _title = new char[10];
        _author = new char[10];
        strcpy(_title, "Undefined");
        strcpy(_author, "Undefined");
    }

    Book(const char *title, const char *author, int year)
        : _year(year)
    {
        _titleLen = strlen(title);
        _authorLen = strlen(author);
        _title = new char[_titleLen + 1];
        _author = new char[_authorLen + 1];
        strcpy(_title, title);
        strcpy(_author, author);
    }

    Book(const Book& book)
    {
        _titleLen = strlen(book._title);
        _authorLen = strlen(book._author);
        _title = new char[_titleLen + 1];
        _author = new char[_authorLen + 1];
        strcpy(_title, book._title);
        strcpy(_author, book._author);
    }

    ~Book()
    {
        delete[] _title;
        delete[] _author;
    }
    void display() 
    {
        std::cout << _title << " " << _author << " " << _year << std::endl;
    }

    void binaryFileWrite(const std::string &fileName = "binaryLibrary.bin")
    {
        std::ofstream file(fileName, std::ios::binary);
        if (!file.is_open()) {
            std::cout << "Failed" << std::endl;
            exit(1);
        }
        else {
            /*file.write(_title, sizeof(_title));
            file.write(_author, sizeof(_author));
            file.write(reinterpret_cast<char*>(&_year), sizeof(int));*/
            file.write(reinterpret_cast<char*>(this), sizeof(Book));
        }
        file.close();
        
    }

    void binaryFileRead(const std::string& fileName = "binaryLibrary.bin")
    {
        std::ifstream file(fileName, std::ios::binary);
        if (!file.is_open()) {
            std::cout << "Failed" << std::endl;
            exit(2);
        }
        else {
            Book read;
            file.read(reinterpret_cast<char*>(&read), sizeof(Book));
            std::cout << read._title << " " << read._author << " " << read._year <<  std::endl;
        }
        file.close();
    }


private:
    char* _title;
    char* _author;
    int _year{ 0 };
    int _titleLen{ 0 };
    int _authorLen{ 0 };
};

#endif

問題肯定出在代碼的這一部分：

void binaryFileRead(const std::string& fileName = "binaryLibrary.bin")
    {
        std::ifstream file(fileName, std::ios::binary);
        if (!file.is_open()) {
            std::cout << "Failed" << std::endl;
            exit(2);
        }
        else {
            Book read;
            file.read(reinterpret_cast<char*>(&read), sizeof(Book));
            std::cout << read._title << " " << read._author << " " << read._year <<  std::endl;
        }
        file.close();
    }

它甚至打印出我想要的控制臺應(yīng)用程序，但仍然不返回0。

我不知道是什么問題，我嘗試了很多，但沒有任何幫助，我甚至認(rèn)為它不能從.bin文件讀取到動態(tài)字符或其他東西。

順便說一句，我的第一個原型沒有使用動態(tài)數(shù)組，我使用了像_title[50]和_author[50]這樣大小不變的數(shù)組，效果很好。我想說完美，但當(dāng)我嘗試使用動態(tài)數(shù)組時，它失敗了。
