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;
    }

}

运行结果：
