C++ Program to Print Right Triangle of Consecutive Row Alphabets Pattern

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

#include<iostream>
using namespace std;

int main()
{
	int rows, val;

	cout << "Enter Right Triangle of Consecutive Row Alphabets Rows = ";
	cin >> rows;

	cout << "Right Triangle of Consecutive Row Alphabets Pattern\n";
	int alphabet = 64;

	for (int i = 1; i <= rows; i++)
	{
		val = i;
		for (int j = 1; j <= i; j++)
		{
			cout << char(alphabet + val) << " ";
			val = val + rows - j;
		}
		cout << "\n";
	}
}

C++ program to print the right angled triangle of consecutive row alphabets pattern using a while loop.

#include<iostream>
using namespace std;

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

	cout << "Enter Right Triangle of Consecutive Row Alphabets Rows = ";
	cin >> rows;

	cout << "Right Triangle of Consecutive Row Alphabets Pattern\n";
	alphabet = 64;
	i = 1;

	while (i <= rows)
	{
		val = i;
		j = 1;

		while (j <= i)
		{
			cout << char(alphabet + val) << " ";
			val = val + rows - j;
			j++;
		}
		cout << "\n";
		i++;
	}
}

This C++ pattern example displays the right angled triangle of consecutive alphabets in each row using the do while loop.

#include<iostream>
using namespace std;

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

	cout << "Enter Right Triangle of Consecutive Row Alphabets Rows = ";
	cin >> rows;

	cout << "Right Triangle of Consecutive Row Alphabets Pattern\n";
	alphabet = 64;
	i = 1;

	do
	{
		val = i;
		j = 1;

		do
		{
			cout << char(alphabet + val) << " ";
			val = val + rows - j;

		} while (++j <= i);
		cout << "\n";

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