C++用for循环怎么打印这个图形呢？

供参考：

#include<iostream>
using namespace std;
int main()
{
    int row, x, y, nrows = 6;
    for (row=1;row<=nrows;row++)        //_________________________)
    {
        for (x=1;x<=nrows-row;x++)      // ____; x <= _____; x++)
            cout << "#";
        for (y=1;y<=2*row-1;y++)      //____; y <=______; y++)
            if (y%2==1)                 //__________________________)
                cout <<"*";              // ___________;
            else
                cout <<"#";              //___________;
        for (x = 1;x<=nrows-row;x++)    //__________; x++)
            cout << "#";
        cout << endl;
    }
    return 0;
