C Program to Print Downward Triangle Mirrored Numbers Pattern

Write a C program to print downward triangle mirrored numbers pattern using for loop.

#include <stdio.h>

int main()
{
	int rows;

	printf("Enter Downward Traingle Mirrored Numbers Rows = ");
	scanf("%d", &rows);

	printf("Downward Traingle of Mirrored Numbers Pattern\n");

	for (int i = 1; i <= rows; i++)
	{
		for (int j = i; j <= rows; j++)
		{
			printf("%d ", j);
		}
		for (int k = rows - 1; k >= i; k--)
		{
			printf("%d ", k);
		}
		printf("\n");
	}
}
C Program to Print Downward Triangle Mirrored Numbers Pattern

This C pattern example prints the downward triangle of mirrored numbers using a while loop.

#include <stdio.h>

int main()
{
	int rows;

	printf("Enter Downward Traingle Mirrored Numbers Rows = ");
	scanf("%d", &rows);

	printf("Downward Traingle of Mirrored Numbers Pattern\n");
	int j, k, i = 1;

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

		k = rows - 1;
		while (k >= i)
		{
			printf("%d ", k);
			k--;
		}

		printf("\n");
		i++;
	}
}
