C++程序打印左减数的平方图案

编写一个C++程序，使用for循环打印左减数的平方。

#include using namespace std;

int main() { int rows;


cout << "Enter Square of Left Dec Numbers Rows = ";
cin >> rows;

cout << "Square of Decrement Numbers from Left Side\\n";

for (int i = rows; i >= 1; i--)
{
	for (int j = i; j < rows; j++)
	{
		cout << j << " ";
	}
	for (int k = rows - i; k < rows; k++)
	{
		cout << rows << " ";
	}
	cout << "\\n";
}

这个C++程序使用while循环来显示左侧递减数的正方形图案。

#include using namespace std;

int main() { int rows, i, j, k;

```pgsql
cout << "Enter Square of Left Dec Numbers Rows = ";
cin >> rows;

cout << "Square of Decrement Numbers from Left Side\\n";
i = rows;

while (i >= 1)
{
	j = i;
	while (j < rows)
	{
		cout << j << " ";
		j++;
	}

	k = rows - i;
	while (k < rows)
	{
		cout << rows << " ";
		k++;
	}

	cout << "\\n";
	i--;
}

Enter Square of Left Dec Numbers Rows = 9
Square of Decrement Numbers from Left Side
9 9 9 9 9 9 9 9 9 
8 9 9 9 9 9 9 9 9 
7 8 9 9 9 9 9 9 9 
6 7 8 9 9 9 9 9 9 
5 6 7 8 9 9 9 9 9 
4 5 6 7 8 9 9 9 9 
3 4 5 6 7 8 9 9 9 
2 3 4 5 6 7 8 9 9 
1 2 3 4 5 6 7 8 9
