C 语言打印左递减数字方阵的程序

编写一个 C 程序，使用 for 循环打印左递减数字的方阵。

#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");
	}
}

本C 程序使用 while 循环显示从左侧开始的递减数字的方阵。

#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
