@[yiyezhiqiu1011](/user/1043489) 你x的赋值不能在输入 $n$ 前啊
by Tjaweiof @ 2023-10-20 13:28:37
@[yiyezhiqiu1011](/user/1043489) 前面几行应该是
```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
int n,a[22][22]={},cnt = 1,y=1,x;
cin >> n;
a[1][n/2+1] = cnt++;
x=n/2+1;
```

@[yiyezhiqiu1011](/user/1043489) 还有一些问题，我再看看
by Tjaweiof @ 2023-10-20 13:30:48
@[yiyezhiqiu1011](/user/1043489) else内，`a[y][x] == cnt++`改成`a[y][x] = cnt++`，前面再加一个
```cpp
y+=2;
if (y > n)
y -= n;
```

改好的代码：
```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
int n,a[22][22]={},cnt = 1,y=1,x;
cin >> n;
a[1][n/2+1] = cnt++;
x=n/2+1;
while (cnt <= n * n)
{
if (--y == 0)
y = n;
if (++x > n)
x = 1;
if (a[y][x] == 0)a[y][x] = cnt++;
else
{
y+=2;
if (y > n)
y -= n;
if (--x == 0){
x = n;
}
a[y][x] = cnt++;
}
}
for (int i = 1; i <= n; i++)
{
for (int j = 1; j <= n; j++)
cout << a[i][j] << " ";
cout << endl;
}
return 0;
}
```
