C Program to Print Downward Triangle Mirrored Alphabets Pattern

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

#include <stdio.h>

int main()
{
	int rows;
	
	printf("Enter Downward Triangle of Mirrored Alphabets Rows = ");
	scanf("%d", &rows);

	printf("Printing Downward Triangle of Mirrored Alphabets Pattern\n");
	int alphabet = 65;

	for (int i = 0; i <= rows - 1; i++)
	{
		for (int j = i; j <= rows - 1; j++)
		{
			printf("%c ", alphabet + j);
		}
		for (int k = rows - 2; k >= i; k--)
		{
			printf("%c ", alphabet + k);
		}
		printf("\n");
	}
}

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

#include <stdio.h>

int main()
{
	int i, j, k, alphabet, rows;
	
	printf("Enter Downward Triangle of Mirrored Alphabets Rows = ");
	scanf("%d", &rows);

	printf("Printing Downward Triangle of Mirrored Alphabets Pattern\n");
	alphabet = 65;
	i = 0;

	while (i <= rows - 1)
	{
		j = i;
		while (j <= rows - 1)
		{
			printf("%c ", alphabet + j);
			j++;
		}

		k = rows - 2;
		while (k >= i)
		{
			printf("%c ", alphabet + k);
			k--;
		}
		printf("\n");
		i++;
	}
}

Enter Downward Triangle of Mirrored Alphabets Rows = 16
