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 result 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 result of the above c program; is as follows:

Enter Triangle of Alphabets in Reverse Rows = 5
