定义描述三维坐标点(x,y,z)的结构体类型变量,完成坐标点的输入/输出,并求两坐标点

Question

要求用c++语言,结构体类型

Answer 1

求两坐标点距离？

#include <iostream>
#include <math.h>
using namespace std;

struct point
{
int x;
int y;
int z;
};

int main()
{
struct point p1,p2;
float d;
cout<<"输入两个坐标点：";
cin>>p1.x>>p1.y>>p1.z;
cin>>p2.x>>p2.y>>p2.z;
cout<<"两个点的坐标分别是："<<endl;
cout<<"("<<p1.x<<","<<p1.y<<","<<p1.z<<")"<<endl;
cout<<"("<<p2.x<<","<<p2.y<<","<<p2.z<<")"<<endl;
d = sqrt((p1.x-p2.x)*(p1.x-p2.x)+(p1.y-p2.y)*(p1.y-p2.y)+(p1.z-p2.z)*(p1.z-p2.z));
cout<<"两点之间的距离："<<d<<endl;

return 0;
}
