@[Wsm4321](/user/859372) sort写错了

应该是
```cpp
sort(x+1,x+4+1)
```
吧？

@[_Haoomff_](/user/368111) 他是对的，他要排序a，b，c

@[Wsm4321](/user/859372) 个人感觉是输出完Not triangle之后要return 0
by Loser_Syx @ 2023-01-08 18:13:32
@[Saint_ying_xtf](/user/852144) 对的，眼瞎了

@[Wsm4321](/user/859372) 楼上的楼上正解
by _Haoomff_ @ 2023-01-08 18:16:09
@[Wsm4321](/user/859372) 能AC
by Loser_Syx @ 2023-01-08 18:41:43
@[Saint_ying_xtf](/user/852144) ac不了
sort后面那个加1也ac不了
by Wsm4321 @ 2023-01-08 18:51:32
@[Wsm4321](/user/859372) sort后面不要加一

你交这个代码
```cpp
#include<iostream>
#include<cmath>
#include<algorithm>
using namespace std;
int main(){
int a,b,c;
cin>>a>>b>>c;
int x[4]={0,a,b,c};
sort(x+1,x+4);
int d=sqrt(x[1]*x[1]+x[2]*x[2]);
int e=sqrt(x[3]*x[3]);
if(x[1]+x[2]<=x[3]){
cout<<"Not triangle"<<endl;
return 0;
}
if(d==e){
cout<<"Right triangle"<<endl;
}
if(d>e){
cout<<"Acute triangle"<<endl;
}
if(d<e){
cout<<"Obtuse triangle"<<endl;
}
if(a==b||a==c||b==c){
cout<<"Isosceles triangle"<<endl;
}
if(a==b&&a==c){
cout<<"Equilateral triangle"<<endl;
}
}
```
