C Program to Print Triangle of Alphabets in Reverse Pattern using For Loop

#include <stdio.h>

int main()
{
	int rows;

	printf("Enter Triangle of Alphabets in Reverse Rows = ");
	scanf("%d", &rows);

	printf("printing Triangle of Alphabets in Reverse Order\n");

	int alphabet = 65;

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

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

Enter Triangle of Alphabets in Reverse Rows = 5
printing Triangle of Alphabets in Reverse Order
    E
   D E
  C D E
 B C D E
A B C D E 

C Program to Print Triangle of Alphabets in Reverse Pattern using While Loop

#include <stdio.h>

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

	printf("Enter Triangle of Alphabets in Reverse Rows = ");
	scanf("%d", &rows);

	printf("printing Triangle of Alphabets in Reverse Order\n");

	alphabet = 65;

	i = rows - 1;
	while (i >= 0)
	{

		j = 0;
		while (j < i)
		{
			printf(" ");
			j++;
		}

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

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