混乱するならシンプルに設計したら？例えばこんな感じ？登録して表示するだけなら簡単でしょ？
#include <stdio.h>
#include <string>
#include <vector>
class Book{
public:
std::string name;
Book(std::string _name) : name(_name){}
void show(){printf("%s\n",name.c_str());}
};
class Books{
public:
std::vector<Book *>m_list;
Books(){}
~Books(){for (auto p : m_list) if (p) delete p;}
void addBook(Book *p){m_list.push_back(p);}
};
int main(){
Books books;
books.addBook(new Book("aa"));books.addBook(new Book("bb"));
books.addBook(new Book("cc"));books.addBook(new Book("dd"));
for (auto p : books.m_list) p->show();
// iterator使いたいなら
//for (auto it = books.m_list.begin(); it != books.m_list.end; it++) (*it)->show();
return 0;
}
