C++实现Object类对象添加到House类及输入存储校验问题

输入格式：标准输入依次接收 <house_number> <房屋物品数量> …… ，直到EOF结束。
要求使用House类的add方法，将每个房屋对应的n个物品添加到House类的成员vector<Object> valuables中，需要先校验输入是否正确存储到House类，以便后续实现每个房屋内所有物品的总价求和功能。

• 核心逻辑错误：读取到当前房屋的物品后，会遍历所有已创建的House实例添加物品，导致所有房屋都被添加了不属于自己的物品，归属关系完全错误
• 冗余变量：全局声明的vector<Object> obj无实际业务作用，仅用于测试打印，可直接从House实例中读取物品信息完成校验
• 性能优化点：总价计算函数传值会产生不必要的对象拷贝，改为传常量引用更合理
