将对象从一个类添加到另一个类

Question

INPUT STDIN -> <street> <city> <house_number> <number of objects of house> <object1> <price1> .......<object-n> <price-n> (until EOF)

我需要使用"add"方法在"房屋";类。
目标:在"House" House"中添加每个House的具体n个对象;类

这是我从现在开始做的:

#include <iostream>
#include <utility>
#include<vector>
#include<string>
using namespace std;
class Object {
public:
string valuable;
float price;
public:
Object() : Object("",0) {}
Object(string v, float p) : valuable(std::move(v)), price(p) {}
string getValuable() {
return valuable;
}
float getPrice()  {
return price;
}
};
class House{
public:
string street;
string city;
uint32_t number;
vector<Object>valuables;
public:
House(): House("","",0){}
House(string s,string c,uint32_t n): street(std::move(s)),city(std::move(c)),number(n){}
string getStreet() {
return street;
}
string getCity() {
return city;
}
uint32_t getNumber() {
return number;
}
uint32_t getValuablesSize() {
return valuables.size();
}
Object getValuable(uint32_t x){
return valuables[x];
}
void add(Object a){
valuables.emplace_back(a);
}
};
float getTotalPrice(House a) {
float sum = 0;
for (int i = 0; i < a.getValuablesSize(); i++) {
sum +=a.valuables[i].getPrice();
}
return sum;
}
int main() {
vector<Object>obj;
vector<House>house;
char object[30],street[30],city[30];
float price;
uint32_t house_number;
int n;
while(cin>>street>>city>>house_number>>n) {
house.emplace_back(string(street),string(city),house_number);
Object a;
for(int i=0;i<n;i++){
cin>>object>>price;  
obj.emplace_back(object,price);
a.valuable=object;
a.price=price;
for(int k=0;k<house.size();k++)
house[k].add(a);          
}      
}
for(int i=0;i<obj.size();i++){
cout<<obj[i].getValuable()<<" "<<obj[i].getPrice()<<endl;
} // trying to print the object vector
for(int i=0;i<house.size();i++){ //trying to verify if i have the correct input
cout<<house[i].getStreet()<<" "<<house[i].getCity()<<" "<<house[i].getNumber()<<" ";
for(int j=0;j<house[i].getValuablesSize();j++) {
cout << house[i].valuables[j].valuable<< " "<<house[i].valuables[j].price<<" ";
} 
cout<<endl;
}
return 0;
}

这就是我的想法:——当我读到，读取对象和价格，然后应该使用add方法，以使vector<Object>valuables可用。
有必要检查输入是否正确地存储在类"house"中，以便继续对每个house中的对象进行求和

与语句

for(int k=0;k<house.size();k++)
house[k].add(a);

添加当前的" value_& quot;对象到目前为止已创建的每个房子。

我建议您单独创建房屋对象，然后将有价值的对象添加到当前房屋中，然后将房屋添加到您的房屋集合中。

可能是这样的:

std::string street;
std::string city;
unsigned house_number;
unsigned n;
while(std::cin >> street >> city >> house_number >> n) {
House current_house(street, city, house_number);
std::string object;
float price;
for(int i = 0; i < n && std::cin >> object >> price; ++i) {
Object a(object, price)
current_house.add(a);
}
house.push_back(current_house);
}
