枚举表示对称方式

#include<iostream>
using namespace std;
enum SymmetricStyle {axisx,axisy,point};
void output(double,double,int);//函数声明
int main()
{
int x,y;
cout<<"请输入点的坐标：";
cin>>x>>y;
cout<<"关于x轴的对称点是：";
output(x,y,axisx);//函数调用
cout<<"关于y轴的对称点是：";
output(x,y,axisy);
cout<<"关于坐标原点的对称点是：";
output(x,y,point);
return 0;
}
void output(double x,double y,int z)//函数定义
{
switch(z)//axisx、axisy、point分别传递给z后转换
{
case axisx:
cout<<"("<<x<<","<<0-y<<")";//容易遗漏“”和<<分隔
break;
case axisy:
cout<<"("<<0-x<<","<<y<<")";
break;
case point:
cout<<"("<<0-x<<","<<0-y<<")";
break;
}
