c++练习--hotdog

要求：
1.根据顾客要求定义hotdog，计算总价
2.按uml类图编写

测试样例：
int main() {
auto h = new Hotdog(new WheatBread());
h->addFood(new Beef());
h->addFood(new Cheese());
h->addFood(new Mustard());
h->addFood(new Onion());
h->addFood(new Onion());
h->addFood(new Tomato());
h->printDetails();
}

#include<iostream>
#include<vector>
using namespace std;class FoodIngredients{int m_price;
public:FoodIngredients(int price){m_price=price;}int getPrice()const{return m_price;}virtual void printDetail()=0;
};class Bread:public FoodIngredients{
public:Bread(int price):FoodIngredients(price){}void printDetail(){cout<<"Bread"<<" "<<getPrice()<<endl;}
};
class Wheat_bread:virtual public Bread{
public:Wheat_bread(int price=7):Bread(price){}void printDetail(){cout<<"Wheat_bread"<<" "<<getPrice()<<endl;}
};
class Honey_break:virtual  public Bread{
public:Honey_break(int price=8):Bread(price){}void printDetail(){cout<<"Honey_break"<<" "<<getPrice()<<endl;}
};class Bacon:virtual public FoodIngredients{
public:Bacon(int price=8):FoodIngredients(price){}void printDetail(){cout<<"Bacon"<<" "<<getPrice()<<endl;}
};
class Beef:virtual public FoodIngredients{
public:Beef(int price=12):FoodIngredients(price){}void printDetail(){cout<<"Beef"<<" "<<getPrice()<<endl;}
};
class Onion:virtual public FoodIngredients{
public:Onion(int price=1):FoodIngredients(price){}void printDetail(){cout<<"Onion"<<" "<<getPrice()<<endl;}
};
class Tomoto:virtual public FoodIngredients{
public:Tomoto(int price=2):FoodIngredients(price){}void printDetail(){cout<<"Tomoto"<<" "<<getPrice()<<endl;}
};
class Lettuce:virtual public FoodIngredients{
public:Lettuce(int price=1):FoodIngredients(price){}void printDetail(){cout<<"Lettuce"<<" "<<getPrice()<<endl;}
};
class Cheese:virtual public FoodIngredients{
public:Cheese(int price=2):FoodIngredients(price){}void printDetail(){cout<<"Chess"<<" "<<getPrice()<<endl;}
};
class Mustard:virtual public FoodIngredients{
public:Mustard(int price=1):FoodIngredients(price){}void printDetail(){cout<<"Mustard"<<" "<<getPrice()<<endl;}
};class Hotdog{Bread *bread;vector<FoodIngredients *> v;//虚基类无法有对象
public:Hotdog(Bread *b){bread=b;}bool addFood(FoodIngredients *f){v.push_back(f);}bool setbreak(Bread *b){}void printDetails(){cout<<"消费表单："<<endl;bread->printDetail();for(vector<FoodIngredients *>::iterator it=v.begin();it!=v.end();it++){FoodIngredients *f=*it;f->printDetail();}}int getTotalPrice(){int total=0;total+=bread->getPrice();for(vector<FoodIngredients *>::iterator it=v.begin();it!=v.end();it++){FoodIngredients *f=*it;total+=f->getPrice();}return total;}
};int main(){auto h = new Hotdog(new Wheat_bread());h->addFood(new Beef());h->addFood(new Cheese());h->addFood(new Mustard());h->addFood(new Onion());h->addFood(new Onion());h->addFood(new Tomoto());h->printDetails();cout <<"总计："<< h->getTotalPrice() << endl;return 0;
}

结果：

消费表单：
Wheat_bread 7
Beef 12
Chess 2
Mustard 1
Onion 1
Onion 1
Tomoto 2
总计：26
