C++ Program to Print K Shape Alphabets Pattern

Write a C++ program to print K shape alphabets pattern using for loop.

#include<iostream>
using namespace std;

int main()
{
	int i, j, alphabet, rows;
     
    cout << "Enter K Shape Alphabets Pattern Row = ";
    cin >> rows;

    cout << "K Shape Alphabets Pattern\n"; 

    for(i = rows - 1; i >= 0; i--)
    {
        alphabet = 65;
    	for(j = 0; j <= i; j++)
		{
            cout << char(alphabet + j) << " ";
        }
        cout << "\n";
    }

    for(i = 1; i < rows; i++)
    {
        alphabet = 65;
    	for(j = 0; j <= i; j++)
		{
            cout << char(alphabet + j) << " ";
        }
        cout << "\n";
    }		
 	return 0;
}

This C++ example prints a K shape pattern of alphabets using a while loop.

#include<iostream>
using namespace std;

int main()
{
	int i, j, alphabet, rows;
     
    cout << "Enter K Shape Alphabets Pattern Row = ";
    cin >> rows;

    cout << "K Shape Alphabets Pattern\n"; 

    i = rows - 1; 
    while(i >= 0)
    {
        alphabet = 65;
        j = 0;
    	while( j <= i)
		{
            cout << char(alphabet + j) << " ";
            j++;
        }
        cout << "\n";
        i--;
    }

    i = 1;
    while( i < rows)
    {
        alphabet = 65;
    	j = 0;
    	while( j <= i)
		{
            cout << char(alphabet + j) << " ";
            j++;
        }
        cout << "\n";
        i++;
    }		
 	return 0;
}

Enter K Shape Alphabets Pattern Row = 10
