Question

c++，定义一个描述三维坐标的结构体类型，然后编写程序完成点输入和输出，并要求两点之间的距离

Answer 1

看错题目了，完善一下

#include<iostream>
#include <cmath>
using namespace std;
struct point {
double a,b,c;
point(double m,double n,double p):a(m),b(n),c(p){};
};
double len(point haha,point xixi){
return sqrt((haha.a-xixi.a)*(haha.a-xixi.a)+(haha.b-xixi.b)*(haha.b-xixi.b)+(haha.c-xixi.c)*(haha.c-xixi.c));}
int main(){
double x1,x2,x3,x4,x5,x6;
cout<<"请输入第一个点的坐标：";
cin>>x1>>x2>>x3;
cout<<"第一点坐标为："<<'('<<x1<<','<<x2<<','<<x3<<')'<<endl;
cout<<"请输入第二个点的坐标";
cin>>x4>>x5>>x6;
cout<<"第二点坐标为："<<'('<<x4<<','<<x5<<','<<x6<<')'<<endl;
point point1(x1,x2,x3),point2(x4,x5,x6);
cout<<"两点距离为："<<len(point1,point2)<<endl;;
return 0;
}
