@[hanyaxin](/user/790535) max得赋值吧

你这个 `max` 的作用是啥。
如果不想用数组，就改成：
```cpp
if(b>a)swap(a,b);
if(c>a)swap(a,c);
```
求个关注QWQ

@[zhangpeinan123](/user/809165) max是一个函数。

我知道，我的意思是，已经找到哪个是最大的了，得把它赋给一个变量。

哦，这样子啊
那这个代码可以吗```
#include<bits/stdc++.h>
using namespace std;
int main()
{
int i,a,n;
cin>>i>>a>>n;
if(a+i<=n||a+n<=i||i+n<=a)
{
cout<<"Not triangle"<<endl;
return 0;
}
if(a*a+i*i>n*n&&a*a+n*n>i*i&&i*i+n*n>a*a)
cout<<"Acute triangle"<<endl;
if(a*a+i*i==n*n||a*a+n*n==i*i||i*i+n*n==a*a)
cout<<"Right triangle"<<endl;
if(a*a+i*i<n*n||a*a+n*n<i*i||i*i+n*n<a*a)
cout<<"Obtuse triangle"<<endl;
if(a==i||a==n||i==n)
cout<<"Isosceles triangle"<<endl;
if(a==i&&a==n&&i==n)
cout<<"Equilateral triangle"<<endl;
return 0;
}
```

“核心代码”
```cpp
if(d[1] * d[1] + d[2] * d[2] == d[3] * d[3]) printf("Right triangle\n");
else if(d[1] * d[1] + d[2] * d[2] > d[3] * d[3]) printf("Acute triangle\n");
else if(d[1] * d[1] + d[2] * d[2] < d[3] * d[3]) printf("Obtuse triangle\n");
if(a == b || b == c || a == c) printf("Isosceles triangle\n");
if(a == b && b == c) printf("Equilateral triangle\n");
```

我艹，你不会是抄题解的吧。你的码风可不是这样的

看看我发现了啥
题解的代码
```
#include <cstdio>
#include <algorithm>
using namespace std;
int a, b, c;
int main() {
scanf("%d%d%d", &a, &b, &c);
int d[4] = {0, a, b, c};
sort(d + 1, d + 4);
if(d[1] + d[2] <= d[3]) {
printf("Not triangle\n");
return 0;
}
if(d[1] * d[1] + d[2] * d[2] == d[3] * d[3]) printf("Right triangle\n");
else if(d[1] * d[1] + d[2] * d[2] > d[3] * d[3]) printf("Acute triangle\n");
else if(d[1] * d[1] + d[2] * d[2] < d[3] * d[3]) printf("Obtuse triangle\n");
if(a == b || b == c || a == c) printf("Isosceles triangle\n");
if(a == b && b == c) printf("Equilateral triangle\n");
return 0;
}
```
你的代码
```
#include <cstdio>
#include <algorithm>
using namespace std;
int a, b, c;
int main() {
scanf("%d%d%d", &a, &b, &c);
int d[4] = {0, a, b, c};
sort(d + 1, d + 4);
if(d[1] + d[2] <= d[3]) {
printf("Not triangle\n");
return 0;
}
if(d[1] * d[1] + d[2] * d[2] == d[3] * d[3]) printf("Right triangle\n");
else if(d[1] * d[1] + d[2] * d[2] > d[3] * d[3]) printf("Acute triangle\n");
else if(d[1] * d[1] + d[2] * d[2] < d[3] * d[3]) printf("Obtuse triangle\n");
if(a == b || b == c || a == c) printf("Isosceles triangle\n");
if(a == b && b == c) printf("Equilateral triangle\n");
return 0;
}
