C Program to Print Inverted Triangle Alphabets Pattern

Write a 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");
	}
}

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

#include <stdio.h>

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

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

	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++;
	}
}

In this C pattern example, we used the do while loop to display the inverted triangle of alphabets.

#include <stdio.h>

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

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

	printf("Printing Inverted Triangle Alphabets Pattern\n");
	alphabet = 65;

	i = 0;

	do
	{
		j = 0;
		do
		{
			printf(" ");

		} while (j++ <= i);

		k = 0;
		do
		{
			printf("%c ", alphabet + k);

		} while (++k <= rows - i - 1);

		printf("\n");

	} while (++i <= rows - 1);
}
