原因是你的数组没定义大小。其实你这个用法我没怎么用过，但是题目给数据范围了，还是定义一下大小吧

```cpp
#include<bits/stdc++.h>
using namespace std;
const int MAX = 1000;
int a[MAX];
int main(){
int n;
cin>>n;
for(int i=0;i<n;i++) cin>>a[i];
cout<<0<<' ';
for(int i=1;i<n;i++){
int tot = 0;
for(int k=i;k>=0;k--) if(a[i] > a[k]) tot++;
cout<<tot<<' ';
}
}
```

数组没有定义范围
