@[Urbosa](/user/1094739) 你这全开int了，应该得有4个开longlong

你在干什么啊，a1~a4 该是 long long 才可以吧

@[Urbosa](/user/1094739)
a1a2那些要设成long long
```cpp
#include <bits/stdc++.h>
using namespace std;
int main() {
int a,b,c,d;
long long a1,a2,a3,a4;
cin>>a>>b;
cin>>c>>d;
a1=a;
a2=b;
a3=c;
a4=d;
if(a*c!=a1*a3||a*d!=a1*a4||b*c!=a2*a3||b*d!=a2*a4){
cout<<"long long int";
}
else{
cout<<"int";
}
return 0;
}
```

我怎么没看懂你在写什么，`a*c!=a1*a3||a*d!=a1*a4||b*c!=a2*a3||b*d!=a2*a4` 的值不应该永远为真吗

@Urbosa,你这个代码是啥意思呀
感觉看完小脑萎缩了
by study_Zzz @ 2024-08-27 11:17:33
这题很简单，比较一下int范围就可以了
