这里给个小建议for(;;)直接写成while(true)就行了，for(;;)不好看

变量定义在main外面是不需要些=0的，除非你要强调什么

@Offending_username 说得对，可以再简化成while(1)

等于不等于的没关系吧？

@Zhuyiming0325

cout << a << " ";

cout << a[j] << " ";

@Zhuyiming0325 输出要改成这个(复制到洛谷上就成这样了，凑合着看吧)

int j=1;
    for(int i=1;i<=n;i++)
    {
        for(j=1;j<=n;j++)
            cout<<a[j+(i-1)*n]<<" ";
        cout<<endl;
    }
