C Program to Print Left Arrow Alphabets Pattern

Write a C program to print left arrow alphabets pattern using for loop.

#include <stdio.h>

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

	printf("Enter Left Arrow Pattern of Alphabets Rows = ");
	scanf("%d", &rows);

	printf("Printing Left Arrow Alphabets Pattern\n");
	alphabet = 65;

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

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

This C program prints the left arrow of the pattern of the alphabet using a while loop.

#include <stdio.h>

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

	printf("Enter Left Arrow Pattern of Alphabets Rows = ");
	scanf("%d", &rows);

	printf("Printing Left Arrow Alphabets Pattern\n");
	alphabet = 65;
	i = rows - 1;

	while (i >= 0)
	{
		j = i;
		while (j >= 0)
		{
			printf("%c ", alphabet + j);
			j--;
		}
		printf("\n");
		i--;
	}

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

This C pattern example uses the do while loop to print left arrow of alphabets.

#include <stdio.h>

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

	printf("Enter Left Arrow Pattern of Alphabets Rows = ");
	scanf("%d", &rows);

	printf("Printing Left Arrow Alphabets Pattern\n");
	alphabet = 65;
	i = rows - 1;

	do
	{
		j = i;
		do
		{
			printf("%c ", alphabet + j);

		} while (--j >= 0);
		printf("\n");

	} while (--i >= 0);

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

		} while (--j >= 0);
		printf("\n");

	} while (++i < rows);
}
