C Program to Print Left Arrow Numbers Pattern using For Loop

#include <stdio.h>
int main()
{
	int rows, i, j;
	printf("Enter Left Arrow Number Pattern Rows = ");
	scanf("%d", &rows);
	printf("Printing Left Arrow Numbers Pattern\n");
	for (i = rows; i >= 1; i--)
	{
		for (j = i; j >= 1; j--)
		{
			printf("%d ", j);
		}
		printf("\n");
	}
	for (i = 2; i <= rows; i++)
	{
		for (j = i; j >= 1; j--)
		{
			printf("%d ", j);
		}
		printf("\n");
	}
}

The result of the above c program; is as follows:

Enter Left Arrow Number Pattern Rows = 5

	i = rows;
	while (i >= 1)
	{
		j = i;
		while (j >= 1)
		{
			printf("%d ", j);
			j--;
		}
		printf("\n");
		i--;
	}
	i = 2;
	while (i <= rows)
	{
		j = i;
		while (j >= 1)
		{
			printf("%d ", j);
