C++ Program to Print Triangle of Mirrored Alphabets Pattern

Write a C++ program to print triangle of mirrored alphabets pattern using for loop.

#include<iostream>
using namespace std;

int main()
{
	int rows;

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

	cout << "Printing Triangle of Mirrored Alphabets Pattern\n";

	int alphabet = 65;

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

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

#include<iostream>
using namespace std;

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

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

	cout << "Printing Triangle of Mirrored Alphabets Pattern\n";

	alphabet = 65;

	i = 0;
	while (i <= rows - 1)
	{
		j = rows - 1;
		while (j >= i)
		{
			cout << " ";
			j--;
		}

		k = 0;
		while (k <= i)
		{
			cout << char(alphabet + k);
			k++;
		}

		l = i - 1;
		while (l >= 0)
		{
			cout << char(alphabet + l);
			l--;
		}
		cout << "\n";
		i++;
	}
}
