Program for triangular patterns of alphabets
  • Difficulty Level : Basic
  • Last Updated : 15 Apr, 2020

Pattern printing has always been an interesting topic in programming languages. It emphasize on the usage of inner and outer loops in nested loops and create beautiful patterns from it.
Below are given some pattern using alphabets. Our task is to write programs for the below given patterns, such that each pattern should print on the basis of given input ‘n’, when n = count of alphabets.

First Pattern :

C++




// C++ code for triangular 
// patterns of alphabets 
#include <bits/stdc++.h>
using namespace std;
  
int main()
{
    int i, j, n = 5;
    for (i = 1; i <= n; i++)
    {
        for (j = i; j <= n; j++)
        {
            cout << (char)('A' - 1 + j) << " ";
        }
        cout << endl;
    }
    return 0;
}

C



#include <stdio.h>
int main()
{
    int i, j, n = 5;
    for (i = 1; i <= n; i++) {
        for (j = i; j <= n; j++) {
            printf("%c", 'A' - 1 + j);
        }
        printf("\n");
    }
    return 0;
}
Java



class GFG
{
public static void main(String args[])
{
    int i, j, n = 5;
    for (i = 1; i <= n; i++) 
    {
        int ch = 65;
            for (j = i; j <= n; j++) 
            {
                System.out.print((char)(ch -1 + j) + " ");
            }
        System.out.print("\n");
    }
}
}
  
// This code is contributed
// by Akanksha Rai
Python3



# Python 3 code for triangular 
# patterns of alphabets 
n = 5
for i in range(1, n + 1):
    for j in range(i, n + 1):
        print(chr(ord('A') - 1 + j), end = ' ')
    print()

using System;
class GFG
{
public static void Main()
{
    int i, j, n = 5;
    for (i = 1; i <= n; i++) 
    {
        int ch = 65;
            for (j = i; j <= n; j++) 
            {
                Console.Write((char)(ch - 1 + j) + " ");
            }
        Console.Write("\n");
    }
}
}

$n = 5;
    for ($i = 1; $i <= $n; $i++)
    {
        for ($j = $i; $j <= $n; $j++) 
        {
            echo chr(65 - 1 + $j)." ";
        }
        echo "\n";
    }

            printf("%c ", 'A' - 1 + i);
        }
        printf("\n");
    }
    return 0;
}
Java



class GFG

    {
        for (j = 1; j <= i; j++) 
        {
            System.out.printf("%c ", 'A' - 1 + i);
        }
        System.out.printf("\n");
    }
    }
}

                         end = ' ')
