你好像没写头文件

而且输出没有换行

你似乎没写头文件，在最前面加上
```cpp
#include<bits/stdc++.h>
```
就好了

@[huangsiyi54033](/user/900996) 输出也要换行，就像这样
```cpp
cout<<"Not triangle<<"\n";
```

~~话说你头文件都不会写还能对四道题~~

前两句if有点问题 改成 (a > c) (b > c)
a < b 可以不要

我写了，只不过它没显示出来

是平方，不是立方

```cpp
if(a*a*a+b*b*b>c*c*c)
{
cout<<"Acute triangle";
}
if(a*a*a+b*b*b==c*c*c)
{
cout<<"Right triangle";
}
if(a*a*a+b*b*b<c*c*c)
{
cout<<"Obtuse triangle";
}
```
改成
```cpp
if(a*a+b*b>c*c)
{
cout<<"Acute triangle";
}
if(a*a+b*b==c*c)
{
cout<<"Right triangle";
}
if(a*a+b*b<c*c)
{
cout<<"Obtuse triangle";
}
```
