main.cpp

设计一个表示直角坐标系上点的位置的Location类

#include<iostream>
#include"location.h"
#include<cmath>
using namespace std;
int main()
{
	 double x1,y1,x2,y2;
	 cout<<"请输入点A的坐标：";
	 cin>>x1>>y1;
	 cout<<"请输入点B的坐标：";
	 cin>>x2>>y2;
     Location m_A(x1,y1),m_B(x2,y2);
     cout<<"使用对象方法求的Distance："<<m_A.Distance(m_B)<<endl;
     Location &m_refA=Location(x1,y1),&m_refB=Location(x2,y2);
	 cout<<"使用引用方法求的Distance："<<m_refA.Distance(m_refB)<<endl;
     Location *m_ptrA=new Location(x1,y1),*m_ptrB=new Location(x2,y2);
     cout<<"使用指针方法求的Distance："<<m_ptrA->Distance(*m_ptrB)<<endl;
     return 0;
