我是一个人 千万别运行下面的代码，会眼瞎

#include <iostream>
using namespace std;
short n;
int main(){
  cin >> n;
short no = 0,noo = 1,noth = 0,num = 1;
	for (int i = 1;i <= n;i++)
	{
		for (int j = 1;j <= noth;j++)
			cout << "   ";
		for (int j = num;j != n * i - no + 1;j++)
		{
			if (num < 10)
			{
				cout << "  " << num;
				num++;
			}
			else
				cout << " " << num;
				num++;
		}
		cout << endl;
		noth++;
		no += noo;
		noo++;
	}
  return 0;
  }
