建议用一种更简单的代码：
```cpp
for(int i = 1; i <= n; i++){
for(int j = 1; j <= i; j++){
if(a[j] > a[i]){
cnt++;
}
}
}
```

```cpp
#include<bits/stdc++.h>
using namespace std;
int a[10000],n,cnt=0;
int main(){
cin>>n;
for(int i=0;i<n;i++) cin>>a[i];
for(int i=0;i<n-1;i++){
for(int j=0;j<n-1;j++){
if(a[j]>a[j+1]){
swap(a[j],a[j+1]);
cnt++;
}
}}
cout <<cnt;
return 0;}
```

睿智代码
```
#include<iostream>
using namespace std;
int main() {
int n, ans = 0;
cin >> n;
int* a = new int[N];
for (int i = 0; i < n; i++)
cin >> a[i];
for (int i = 0; i < n-1; i++) {
for (int j = 0; j < n-i-1; j++) {
if (a[j] > a[j+1]) {
int tmp = a[j];
a[j] = a[j+1];
a[j+1] = tmp;
ans++;
}
}
}
cout << ans << endl;
return 0;
}
```
