using namespace std;

int main()
{
	int rows;

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

	cout << "Printing Inverted Right Triangle Alphabets Pattern\n";
	int alphabet = 65;

	for (int i = rows - 1; i >= 0; i--)
	{
		for (int j = 0; j <= i; j++)
		{
			cout << char(alphabet + j);
		}
		cout << "\n";
	}
}

This C++ example prints the inverted right angled triangle pattern of alphabets using a do while loop.

#include<iostream>
using namespace std;

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

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

	cout << "Printing Inverted Right Triangle Alphabets Pattern\n";
	alphabet = 65;

	i = rows - 1;
	do
	{
		j = 0;
		do
		{
			cout << char(alphabet + j);

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

	} while (--i >= 0);
}
