Program To Print Pattern 3

Program To Print Pattern 3 on fibonacci, factorial, prime, armstrong, swap, reverse, search, sort, stack, queue, array, linkedlist, tree, graph, pattern, string etc.

<< Back to PROGRAM

Write a program to print the following pattern.

*000*000*

0*00*00*0

00*0*0*00

000***000

Algorithm

  • STEP 1: START
  • STEP 2: SET lines=4
  • STEP 3: Initialize i and j
  • STEP 4: SET i =1
  • STEP 5: REPEAT STEP 6 to 15 UNTIL i less than or equals to line
  • STEP 6: SET j=1
  • STEP 7: REPET STEP 8 and 9 UNTIL j is less than or equals to lines
  • STEP 8: IF i is equal to j PRINT * ELSE PRINT 0
  • STEP 9: SET j = j + 1
  • STEP 10: DECREMENT j by 1 and PRINT *
  • STEP 11: REPEAT STEP 12 and 13 UNTIL j is greater than 0
  • STEP 12: IF i is equals to j PRINT * ELSE PRINT 0
  • STEP 13: SET j = j - 1
  • STEP 14: PRINT a new line
  • STEP 15: SET i = i + 1
  • STEP 16: EXIT

Solution:

C Program:

#include <stdio.h>
int main()
{
  int lines=4;
  int i,j;
  for(i=1;i<=lines;i++){// this loop is used to print lines
      for(j=1;j<=lines;j++){// this loop is used to print * in a line
          if(i==j)
            printf("*");
            else
          printf("0");
      }
      j--;
      printf("*");
      while(j>=1){// this loop is used to print * in a line
          if(i==j)
          printf("*");
          else
          printf("0");
          j--;
      }
    printf("\n");
  }
    return 0;
}

Output:

*000*000*
0*00*00*0
00*0*0*00
000***000

Java Program:

public class pattern{
     public static void main(String[] args){
    int lines=4;
    int i,j;
    for(i=1;i<=lines;i++){// this loop is used to print lines
      for(j=1;j<=lines;j++){// this loop is used to print * in a line
          if(i==j)
             System.out.print("*");
            else
           System.out.print("0");
      }
      j--;
       System.out.print("*");
      while(j>=1){// this loop is used to print * in a line
          if(i==j)
           System.out.print("*");
          else
           System.out.print("0");
          j--;
      }
    System.out.println("");
  }
         }
}

Output:

*000*000*
0*00*00*0
00*0*0*00
000***000

C# Program:

using System;
					
public class Program
{
	public static void Main()
	{
	int lines=4;
  int i,j;
  for(i=1;i<=lines;i++){// this loop is used to print lines
      for(j=1;j<=lines;j++){// this loop is used to print lines
          if(i==j)
            Console.Write("*");
            else
          Console.Write("0");
      }
      j--;
      Console.Write("*");
      while(j>=1){// this loop is used to print lines
          if(i==j)
          Console.Write("*");
          else
          Console.Write("0");
          j--;
      }
    Console.WriteLine("");
  }
	}
}

Output:

*000*000*
0*00*00*0
00*0*0*00
000***000

PHP Program:

<?php
$lines=4;
$i;
$j;
  for($i=1;$i<=$lines;$i++){// this loop is used to print lines
      for($j=1;$j<=$lines;$j++){ // this loop is used to print lines
          if($i==$j)
            echo "*";
            else
          echo "0";
      }
      $j--;
      echo "*";
      while($j>=1){// this loop is used to print lines
          if($i==$j)
          echo "*";
          else
          echo "0";
          $j--;
      }
    echo "<br>";
  }
?>

Output:

*000*000*
0*00*00*0
00*0*0*00
000***000

Python Program:

lines=4
i=1
j=1
while i<=lines:	#this loop is used to print lines
    j=1
    while j<=lines:		#this loop is used to print lines
        if i==j:
            print("*", end='', flush=True)
        else :
            print("0", end='', flush=True)
        j=j+1
    j=j-1;
    print("*", end='', flush=True)
    while j>=1:	#this loop is used to print lines
        if i==j:
            print("*", end='', flush=True)
        else :
            print("0", end='', flush=True)
        j=j-1
    print("");
    i=i+1

Output:

*000*000*
0*00*00*0
00*0*0*00
000***000
