C++编程学习之贺利坚老师的C++第一周项目1

【项目1 - 用枚举表示对称方式】设计函数，可以按指定的方式，输出一个平面点的对称点

#include<iostream>using namespace std;enum SymmetricStyle {axisx, axisy, point};//分别表示按x轴, y轴, 原点对称三种方式void output(double,double,SymmetricStyle);int main(){    int x,y;    cout<<"输入点的坐标：";    cin>>x>>y;    cout<<"关于x轴的对称点是：";    output(x,y,axisx);    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,SymmetricStyle m){switch(m){case axisx:cout<<"("<<x<<","<<(-y)<<")"<<endl;break;case axisy:cout<<"("<<(-x)<<","<<y<<")"<<endl;break;case point:cout<<"("<<(-x)<<","<<(-y)<<")"<<endl;break;}}
