Print Triangle with Repeated Character (Decreasing Order)

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

In this program we are going to see how to print triangle with repeated character in decreasing order pattern.

Example-1

When character=h 
and row value=4

   h
  g g
 f  f  f
e e e e
Example-2:

When character=F 
and row value=5

       F
     E E
   D D D
  C C C C
 B B B B B

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

Practice Java programming from home without using any fancy software just by tapping on this Simple Java Programs for Beginners tutorial.

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 newline.

Java Code to Print Triangle with Repeated Character (Decreasing Order) 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 = 0; row < row_count; row++)
            {
                //Inner loop to print space
                for (col = row_count; col >row; col--)
                {
                    System.out.print(" ");
                    
                }
                //Inner loop to print character
                for(col = 0; col<=row; col++)
                {
                    System.out.print((char)(asciiValue-row)+" ");
                }
                //Prints a newline
                System.out.println();
            }
        }
    }
}


Output:

Character : F
Rows : 5

      F
     E E
   D D D
  C C C C
 B B B B B

C Code to Print Triangle with Repeated Character (Decreasing Order) 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 = 0; row < row_count; row++)
        {
            //Inner loop to print space
            for (col = row_count; col > row; col--)
            {
                printf(" ");
            }
            //Inner loop to print character
            for (col = 0; col <= row; col++)
            {
                printf("%c ", (char)(asciiValue - row));
            }
            //Prints a newline
            printf("\n");
        }
    }
    return 0;
}
Output:

Character : F
Rows : 5

      F
     E E
   D D D
  C C C C
 B B B B B

C++ Code to Print Triangle with Repeated Character (Decreasing Order) 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 = 0; row < row_count; row++)
        {
            //Inner loop to print space
            for (col = row_count; col > row; col--)
            {
                cout << " ";
            }
            //Inner loop to print characters
            for (col = 0; col <= row; col++)
            {
                cout << (char)(asciiValue - row) << " ";
            }
            //Prints a newline
            cout << endl;
        }
    }
    return 0;
