双十一超市购物优惠系统

C++的第一次考试。。。。。。

题意：实现超市优惠统计，积分兑换查询

题解：对于这个程序的划分，包括类的定义，继承类的定义，设置main函数，和实现优惠计算的函数Money2_0602dky。首先定义一个优惠商品的类，其次，由这个商品类继承出饮品类，玩具类，粮食类，日用品类和服饰类。在main函数中，我首先设置了系统开启码，然后下面列举了一系列优惠商品。接下来我设置了一个积分礼品兑换查询系统，接下来是利用函数计算优惠后的便民优惠查询系统。

AC代码：

#include<iostream.h>
#include<string.h>
double Money2_0602dky(double money1);
