@zhanwang 函数名重复

变量名 y1 会出问题

by bzzltl @ 2023-09-06 19:42:12

@zhanwang 括号匹配有问题

#include<bits/stdc++.h>
using namespace std;
int x1,y1,x2,x3,y2,y3;
int main(){
    cin>>x1>>y1>>x2>>y2>>x3>>y3;
    double sum=0;
    sum+=sqrt(pow((max(x1,x2)-min(x1,x2)),2)+pow((max(y1,y2)-min(y1,y2)),2));
    sum+=sqrt(pow((max(x2,x3)-min(x2,x3)),2)+pow((max(y2,y3)-min(y2,y3)),2));
    sum+=sqrt(pow((max(x1,x3)-min(x1,x3)),2)+pow((max(y1,y3)-min(y1,y3)),2));
    cout<<fixed<<setprecision(3)<<(double)sum;
    return 0;
}

以及万能头下不要用y1做变量名

by xuchuhan @ 2023-09-06 19:43:46

建议更换变量名。

@zhanwang

by zhanwang @ 2023-09-06 19:47:53

@bzzltl @xuchuhan @Pitiless_boy 谢谢大佬，把y1改了之后就能编译了

by bzzltl @ 2023-09-06 19:50:37

@zhanwang 函数名没有重复，那个人说的有问题

by zhanwang @ 2023-09-06 19:53:31

@bzzltl 嗯嗯

by _8008008 @ 2023-09-06 20:18:59

@bzzltl 有函数用这个作为函数名的吗iostream+手写函数的表示很懵逼

by bzzltl @ 2023-09-06 20:19:52

@_8008008 你指的哪一个？
