5个WA??????????????????????????????????????????????
#include <bits/stdc++.h>
using namespace std;
int main(){
double x1,y1,x2,y2,x3,y3,a,b,c;
cin>>x1>>y1>>x2>>y2>>x3>>y3;
a=sqrt(pow(x2-x1,2)*pow(y2-y1,2));
b=sqrt(pow(x3-x2,2)*pow(y3-y2,2));
c=sqrt(pow(x1-x3,2)*pow(y1-y3,2));
cout<<fixed<<setprecision(2);
cout<<a+b+c;
} 嘤嘤嘤(;´༎ຶД༎ຶ`)

pow函数有精度差，建议手写平方

公式输错了

题目写加法你写仨乘

@032o35 你自己试了吗？

@Weirdle 抱歉，我是把我手写平方贴上来了，以为就是这个错

sqrt(pow(x1-x2,2)+pow(y1-y2)) 其他也这样改
