#include<bits/stdc++.h>
using namespace std;
double x1,y1,x2,y2,x3,y3,s=0;
int main(){
    cin>>x1>>1>>x2>>y2>>x3>>y3;
    double s=sqrt((x1-x2)*(x1-x2)+(y1-y2)*(y1-y2))+sqrt((x1-x3)*(x1-x3)+(y1-y3)*(y1-y3))+sqrt((x2-x3)*(x2-x3)+(y2-y3)*(y2-y3));
    printf("%.2lf",s);
    return 0;    
}

@ivyjiao 大佬能不能靠换头文件使它正常通过

by ivyjiao @ 2022-08-31 21:34:05

@EDang20001 不行吧

@ivyjiao 只能把变y1换了吗？

@EDang20001 sqrt函数是cmath的

我先下线了
