精选优质文档-倾情为你奉上一、程序名称：自动售货机二、程序功能：将程序中的数组输出，并分别按从大到小和从小到大的顺序输出，在输出4.4三、程序设计及实现。1、主函数：main()实现程序的主界面2、public公有成员、private私有成员3、数据设置为string字符串类型、float单精度类型、int整形4、输出：cout<< <<用来输出显示的内容5、选择语句：switch() case1：6、实现简单的界面设计，类的成员变量，调用函数，循环，if语句可操作销售、支付、上架、找零等功能四、程序运行结果：五、程序代码/头文件 #include <iostream>#include <string>#include <vector>#include <cstdlib>using namespace std; /命名空间struct DrinkDrink(float pr, string n);string name; /字符串类型 float price; /单精度 int account; /整形 ;class Vendingpublic: Vending(); /类的公有成员inline void showStorage() const cout << "可乐：" << m_cola->account << endl << "奶茶：" << m_milkT->account << endl;cout << "凉茶：" << m_T->account << endl;inline void showSoldNum() constcout << m_cola->name << endl << "销售量：" << m_soldCola << endl;cout << "销售额：" << m_soldCola*(m_cola->price) << endl;cout << m_milkT->name << endl << "销售量：" << m_soldMilkTea << endl;cout << "销售额：" << m_soldMilkTea*(m_milkT->price) << endl;cout << m_T->name << endl << "销售量：" << m_soldTea << endl;cout << "销售额：" << m_soldTea*(m_T->price) << endl;void addStore();void sellItem();void popMenu();private: /类的私有成员 Drink *m_cola, *m_milkT, *m_T;int m_soldCola, m_soldMilkTea, m_soldTea;Drink:Drink(float pr, string n):name(n), price(pr), account(10) /名称、价格、库存数量 /销售界面Vending:Vending():m_soldCola(0), m_soldMilkTea(0), m_soldTea(0)m_cola = new Drink(float(2.8), "可乐");m_milkT = new Drink(float(3.0), "奶茶");m_T = new Drink(float(3.5), "凉茶");/上架界面 void Vending:addStore()cout << "请选择要上架的商品：n1.可乐n2.奶茶n3.凉茶n"int n, count;cin >> n;if(n > 3)cout << "选择错误" << endl;return;cout << "请输入要上架的数量："cin >> count;if(n = 1)m_cola->account += count;else if(n = 2)m_milkT->account += count;else if(n = 3)m_T->account += count;elsecout << "操作失败" << endl;return;cout << "操作完成" << endl;/销售界面 void Vending:sellItem()cout << "1." << m_cola->name << "：" << endl;cout << "价格：" << m_cola->price << ends << "库存：" << m_cola->account << (m_cola->account = 0 ?
