C Program to Print Triangle of Mirrored Numbers Pattern

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

#include <stdio.h>

int main()
{
	int rows;

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

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

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

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

#include <stdio.h>

int main()
{
	int i, j, k, l, rows;
	
	printf("Enter Traingle Mirrored Numbers Rows = ");
	scanf("%d", &rows);

	printf("Printing Traingle of Mirrored Numbers Pattern\n");
	i = 1;

	while (i <= rows)
	{
		j = rows;
		while (j > i)
		{
			printf(" ");
			j--;
		}

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

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

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