标准答案输出是第一张照片，我的输出是第二张照片，看不懂也不明白错在哪里

![img](https://img-mid.csdnimg.cn/release/static/image/mid/ask/140523238666167.jpg "#left")

for (i = 0; i < n; i++)
{
for (j = 0; j < n; j++)
{
scanf("%c", &a[i][j]);
}
}
你所有输入字符都在同一行吗？如果分成多行，那么每行的结束符你必须加getchar()接收才行。
改为：

for (i = 0; i < n; i++)
{
        for (j = 0; j < n; j++)
             scanf("%c", &a[i][j]);
        getchar();
}
