Program to Print Downward Triangle Character Pattern

In the previous article, we have discussed Java Program to Print Triangle with Repeated Character (Decreasing Order) Pattern

In this program we are going to see how to print downward triangle character pattern.

Example-1

When character=h 
and row value=3

   h i j
    h i
     h
Example-2:

When character=A 
and row value=5

  A B C D E
   A B C D
    A B C
     A B
      A

Now, let’s see the actual program to print it.

Interested in programming and want to excel in it by choosing the short ways. Then, practicing with the available Java Program list is mandatory.

Approach:

  • Enter the character and store it in a variable c.
  • Then enter total row and store it in an integer variable row_count.
  • Take one outer for loop to iterate the rows.
  • Take one inner loop to iterate the columns and print the character.
  • After each iteration print a new line.

Java to Print Downward Triangle Character Pattern

import java.util.Scanner;
class Main
{
public static void main(String[] args){
    Scanner scan = new Scanner(System.in);
    //Taking character to be printed as input from the user
    System.out.print("Character : ");
    char c = scan.next().charAt(0);

    //Taking number of rows as input from the user
    System.out.print("Rows : ");
    int row_count = scan.nextInt();

    int row, col;
    //Converting the character to its ascii value
    int asciiValue = (int) c;

    //Checks whether the character is a letter or not
    if(asciiValue>=65&&asciiValue<=122)
    {
        
        //Outer loop to iterate rows
        for (row = 1; row <= row_count; row++)
        {
            //Inner loop to print space
            for (col = 0; col <=row; col++)
            {
                System.out.print(" ");
                
            }
            //Inner loop to print character
            for(col = 0; col<=row_count-row; col++)
            {
                System.out.print((char)(asciiValue+col)+" ");
            }
            //Prints a newline
            System.out.println();
        }
    }
}
}


Output:

Character : A
Rows : 5

A B C D E
  A B C D
   A B C
    A B
      A

C to Print Downward Triangle Character Pattern

#include <stdio.h>

int main()
{
    //Taking character to be printed as input from the user
    printf("Character : ");
    char c;
    scanf("%c", &c);

    //Taking number of rows as input from the user
    printf("Rows : ");
    int row_count;
    scanf("%d", &row_count);

    int row, col;
    //Converting the character to its ascii value
    int asciiValue = (int)c;

    //Checks whether the character is a letter or not
    if (asciiValue >= 65 && asciiValue <= 122)
    {
        //Outer loop to iterate rows
        for (row = 1; row <= row_count; row++)
        {
            //Inner loop to print space
            for (col = 0; col <= row; col++)
            {
                printf(" ");
            }
            //Inner loop to print character
            for (col = 0; col <= row_count - row; col++)
            {
                printf("%c ", (char)(asciiValue + col));
            }
            //Prints a newline
            printf("\n");
        }
    }
    return 0;
}



Output:

Character : A
Rows : 5

A B C D E
  A B C D
   A B C
    A B
      A

C++ to Print Downward Triangle Character Pattern

#include <iostream>
using namespace std;
int main(int argc, char const *argv[])
{
    //Taking character to be printed as input from the user
    cout << "Character : ";
    char c;
    cin >> c;

    //Taking number of rows as input from the user
    cout << "Rows : ";
    int row_count;
    cin >> row_count;

    int row, col;
    //Converting the character to its ascii value
    int asciiValue = (int)c;

    //Checks whether the character is a letter or not
    if (asciiValue >= 65 && asciiValue <= 122)
    {
        //Outer loop to iterate rows
        for (row = 1; row <= row_count; row++)
        {
            //Inner loop to print space
            for (col = 0; col <= row; col++)
            {
                cout << " ";
            }
            //Inner loop to print characters
            for (col = 0; col <= row_count - row; col++)
            {
                cout << (char)(asciiValue + col) << " ";
            }
            //Prints a newline
            cout << endl;
        }
    }
    return 0;
}


Output:

Character : A
Rows : 5

  A B C D E
   A B C D
    A B C
     A B
      A
