buzhi不知道哪里错了

```

```#include <iostream>
using namespace std;</iostream>

int main ()
{
int flag=0;
char arr[3][3];

for (int i=0;i<3;i++)
{
    for (int j=0;j<3;j++)
        {
        cin>>arr[i][j];
        }
}
//判断是否交叉
if (arr[1][1]==arr[2][2]==arr[0][0]||arr[1][1]==arr[2][0]==arr[0][2])
        if (arr[1][1]=='K')
            cout<<"KiKi wins!\n";
        else
            cout<<"BoBo wins!\n";
else//当不交叉执行下面

{for (int i=0;i<3;i++)//是否成行,列
    {
        if (arr[i][0]==arr[i][1]==arr[i][2])//cheng hang
            {if (arr[i][1]=='K')
                {cout<<"KiKi wins!\n";
                 flag=1;}
            else
                cout<<"BoBo wins!\n";
                 flag=1;
            }
        if (arr[0][i]==arr[1][i]==arr[2][i])//cheng lie 
            {if (arr[1][i]=='K')
                {cout<<"KiKi wins!\n";

    }
