Program to Print Pant Style Character Pattern

In the previous article, we have discussed Java Program to Print letters of a string in Right Angled Triangle Character Pattern

In this program we are going to see how to print pant style character pattern.

Example-1

When row value=5

ABCDEFEDCBA
ABCDE  EDCBA
ABCD      DCBA
ABC           CBA
AB                BA
A                    A
Example-2:

When row value=9

ABCDEFGHIJIHGFEDCBA
ABCDEFGHI IHGFEDCBA
ABCDEFGH   HGFEDCBA
ABCDEFG        GFEDCBA
ABCDEF             FEDCBA
ABCDE                 EDCBA
ABCD                     DCBA
ABC                          CBA
AB                              BA
A                                  A

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

Don’t stop learning now. Get hold of all the important Java fundamentals with the Simple java program example guide and practice well.

Approach:

  • Enter total row and store it in an integer variable row_count.
  • Take one outer for loop to iterate the rows,
  • Inside the for loop, take three inner for loops, one to print the space and the other for characters.
  • After each iteration print a new line

Java Code to Print Pant Style Character Pattern

import java.util.Scanner;
public class Main
{
public static void main(String[] args)  
{  
    Scanner scan = new Scanner(System.in);

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

    int row,col;
    // Ascii value if 'A'
    int asciiAlpha = 65;

    // Outer Loop
    for(row = 0; row<=row_count; row++)
    {
        // Inner loop to print character
        for(col=0;col<=row_count-row;col++)
        {
            System.out.print((char)(asciiAlpha+col));
        }

        // Inner loop to print space
        for(col=1;col<=row*2-1;col++)
        {
            System.out.print(" ");
        }

        // Inner loop to print character
        for(col = row_count-row;col>=0; col--)
        {
            if(col!=row_count)
            System.out.print((char)(asciiAlpha+col));
        }

        // Prints a newline
        System.out.println();
    }
}  
}

Output:

Rows : 5

ABCDEFEDCBA
ABCDE  EDCBA
ABCD      DCBA
ABC           CBA
AB               BA
A                   A

C Code to Print Pant Style Character Pattern

#include <stdio.h>
#include <string.h>

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

    int row, col;

    // Ascii value if 'A'
    int asciiAlpha = 65;

    // Outer Loop
    for (row = 0; row <= row_count; row++)
    {
        // Inner loop to print character
        for (col = 0; col <= row_count - row; col++)
        {
            printf("%c", (asciiAlpha + col));
        }

        // Inner loop to print space
        for (col = 1; col <= row * 2 - 1; col++)
        {
            printf(" ");
        }

        // Inner loop to print character
        for (col = row_count - row; col >= 0; col--)
        {
            if (col != row_count)
                printf("%c", (asciiAlpha + col));
        }

        // Prints a newline
        printf("\n");
    }
    return 0;
}


Output:

Rows : 5

ABCDEFEDCBA
ABCDE  EDCBA
ABCD      DCBA
ABC           CBA
AB                BA
A                    A

C++ Code to Print Pant Style Character Pattern

#include <iostream>
#include <cstring>
#include <string.h>
using namespace std;
int main(int argc, char const *argv[])
{
    //Taking total rows as input from the user
    cout << "Rows : ";
    int row_count;
    cin >> row_count;

    int row, col;

    // Ascii value if 'A'
    int asciiAlpha = 65;

    // Outer Loop
    for (row = 0; row <= row_count; row++)
    {
        // Inner loop to print character
        for (col = 0; col <= row_count - row; col++)
        {
            cout << (char)(asciiAlpha + col);
        }

        // Inner loop to print space
        for (col = 1; col <= row * 2 - 1; col++)
        {
            cout << " ";
        }

        // Inner loop to print character
        for (col = row_count - row; col >= 0; col--)
        {
            if (col != row_count)
                cout << (char)(asciiAlpha + col);
        }

        // Prints a newline
        cout << endl;
    }
    return 0;
}

Output:

Rows : 5

ABCDEFEDCBA
ABCDE  EDCBA
ABCD      DCBA
ABC           CBA
AB                BA
A                    A
