C Program to Print Inverted Triangle Alphabets Pattern using For Loop

#include <stdio.h>
int main()
{
	int rows;
	printf("Enter Inverted Triangle of Alphabets Rows = ");
	scanf("%d", &rows);
	printf("Printing Inverted Triangle Alphabets Pattern\n");
	int alphabet = 65;
	for (int i = 0; i <= rows - 1; i++)
	{
		for (int j = 0; j <= i; j++)
		{
			printf(" ");
		}
		for (int k = 0; k <= rows - i - 1; k++)
		{
			printf("%c ", alphabet + k);
		}
		printf("\n");
	}
}

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

	printf("Printing Inverted Triangle Alphabets Pattern\n");
	alphabet = 65;
	i = 0;
	while (i <= rows - 1)
	{
		j = 0;
		while (j <= i)
		{
			printf(" ");
			j++;
		}
		k = 0;
		while (k <= rows - i - 1)
		{
			printf("%c ", alphabet + k);
			k++;
		}
		printf("\n");
		i++;
	}
}
