可以使用STL中的list容器对该数据进行存储和读取操作。需要注意的是,list容器中存储的是Book对象,因此需要重载Book类的输入输出运算符。以下是一个示例代码:
```c++
#include <iostream>
#include <list>
#include <fstream>
using namespace std;
class Time {//时间类
//...
};
class Book {//书籍类
private:
string name;
string author;
string publisher;
int pages;
Time latestTime;
int stock;
double price;
public:
//重载输入输出运算符
friend ostream& operator<<(ostream& os, const Book& b) {
os << b.name << " " << b.author << " " << b.publisher << " "
<< b.pages << " " << b.latestTime << " " << b.stock << " " << b.price << endl;
return os;
}
friend istream& operator>>(istream& is, Book& b) {
is >> b.name >> b.author >> b.publisher >> b.pages
>> b.latestTime >> b.stock >> b.price;
return is;
}
};
int main() {
list<Book> books;
//写入文件
ofstream out("books.txt");
if (!out) {
cerr << "Cannot open file" << endl;
return 1;
}
for (const auto& book : books) {
out << book;
}
out.close();
//从文件中读取
ifstream in("books.txt");
if (!in) {
cerr << "Cannot open file" << endl;
return 1;
}
Book book;
while (in >> book) {
books.push_back(book);
}
in.close();
//...
return 0;
}
```
在该示例中,使用了STL中的list容器对Book对象进行存储,并通过重载输入输出运算符实现了将Book对象写入文件和从文件中读取Book对象的操作。
