首先你这个m应该等于i+1，因为是VK不是KV
其次当是VK是应该标注一下以免和VV或KK重合
改进代码如下
```cpp
#include <bits/stdc++.h>
using namespace std;
int N = 1000;
int main() {
char a[N];
int n, ans = 0;
cin >> n;
for (int i = 1; i <= n; i++) {
cin >> a[i];
}
for (int i = 1; i <= n; i++) {
int m = i + 1;
if (a[i] == 'V' && a[m] == 'K') {
a[i] = 'v';
a[m] = 'k';
ans++;
}
}
for (int i = 1; i <= n; i++) {
int l = i + 1;
if (a[i] == 'V' && a[l] == 'V') {
ans++;
break;
}
if (a[i] == 'K' && a[l] == 'K') {
ans++;
break;
}
}
cout << ans;
return 0;
}
```
