数组魔方阵最后一点点出了个小BUG求找啊~~~

Question

#include

试着看了一下你的代码，跳转太多，逻辑不分明，实在是看不下去了。你还是看一下这个吧！
#include
#define N 20
void main()
{
int a[N][N],n,i,j,k;
while(1)
{
printf("请输入一个正整数n(n<=20,n为奇数):");
scanf("%d",&n);
if(n!=0&&n<=20&&n%2!=0)
{
printf("%d阶魔方阵.\n",n);
break;
}
}
for(i=0;i for(j=0;j a[i][j]=0;
i=0;
j=n/2;
a[i][j]=1;
k=2;
while(k {
i-=1;
j+=1;
if(in-1)
{
i+=2;
j-=1;
}
else
{
if(i i=n-1;
if(j>n-1)
j=0;
}
if(a[i][j]==0)
a[i][j]=k;
else
{
i+=2;
j-=1;
a[i][j]=k;
}
k++;
}
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
printf("%4d",a[i][j]);
printf("\n");
}
}
