C Program to Print Right Triangle of Mirrored Numbers Pattern

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

#include <stdio.h>

int main()
{
	int rows;

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

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

This C program prints the right angled triangle pattern of mirrored numbers using a while loop.

#include <stdio.h>

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

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

	printf("Right Traingle of Mirrored Numbers\n");
	
	i = 1;
	while (i <= rows)
	{
		j = 1;
		while (j <= i)
		{
			printf("%d", j);
			j++;
		}

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

Enter Right Traingle Mirrored Numbers Rows = 10

This C example uses the rMirroredNumbers function to print the right angled triangle of mirrored numbers pattern.

#include <stdio.h>

void rtMirroredNumbers(int rows);

int main()
{
	int rows;

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

	printf("Right Traingle of Mirrored Numbers\n");
	rtMirroredNumbers(rows);
}

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

Enter Right Traingle Mirrored Numbers Rows = 13
