C语言程序打印左数减法的正方形图案

编写一个C语言程序，使用for循环打印左减数的正方形图案。

#include <stdio.h

int main() { int rows;

printf("Enter Square of Left Dec Numbers Rows = ");
scanf("%d", &rows);

printf("Square of Decrement Numbers from Left Side\\n");

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

这个C语言程序使用while循环显示左边的递减数的正方形图案。

#include <stdio.h>.

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


printf("Enter Square of Left Dec Numbers Rows = ");
scanf("%d", &rows);

printf("Square of Decrement Numbers from Left Side\\n");
i = rows;

while (i >= 1)
{
	j = i;
	while (j < rows)
	{
		printf("%d ", j);
		j++;
	}

	k = rows - i;
	while (k < rows)
	{
		printf("%d ", rows);
		k++;
	}

	printf("\\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
