帮我用C++写一份完整的图书管理系统,复杂一点,能在控制台进行操作,需要详细的代码注释和需要设计基类和派生类,需要书籍类、图书类型类、图书类,要有较为完整的代码注释。

好的,下面是一份C++的图书管理系统示例代码,包括了基类和派生类的设计、增删改查等功能,并在控制台进行操作。代码中也包含了注释,以方便您理解。请注意,这份代码可能并不是最完美的,您可以根据自己的需求进行修改和完善。
```cpp
#include <iostream>
#include <string>
#include <vector>
using namespace std;
// 基类:图书类型
class BookType {
private:
int typeId; // 图书类型编号
string typeName; // 图书类型名称
public:
BookType(int id, string name) {
typeId = id;
typeName = name;
}
int getTypeId() {
return typeId;
}
string getTypeName() {
return typeName;
}
};
// 基类:图书
class Book {
private:
int id; // 图书编号
string name; // 图书名称
string author; // 作者
int typeId; // 图书类型编号
string publish; // 出版社
int price; // 价格
public:
Book(int id, string name, string author, int typeId, string publish, int price) {
this->id = id;
this->name = name;
this->author = author;
this->typeId = typeId;
