C Program to Print Right Triangle of Consecutive Alphabets Pattern

Write a C program to print right triangle of consecutive alphabets pattern using for loop.

#include <stdio.h>

int main()
{
	int rows;

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

	printf("Right Triangle of Consecutive Alphabets Pattern\n");
	int alphabet = 65;

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

This C program prints the right angled triangle pattern of consecutive alphabets using a while loop.

#include <stdio.h>

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

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

	printf("Right Triangle of Consecutive Alphabets Pattern\n");
	alphabet = 65;

	i = 0;

	while (i <= rows - 1)
	{
		j = 0;

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

Enter Right Triangle of Consecutive Alphabets Rows = 9

This C example uses the do while loop to print the right angled triangle of consecutive column alphabets pattern.

#include <stdio.h>

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

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

	printf("Right Triangle of Consecutive Alphabets Pattern\n");
	
	alphabet = 65;

	i = 0;

	do
	{
		j = 0;

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

		} while (++j <= i);

		printf("\n");

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