Program to Print Pattern 17

Program to print the following pattern

Algorithm

Start
Let i be an integer number.
Let j be an integer number.
Let n be a integer number and initialize by 1.
Repeat step 6 to 9 until all value parsed.
Set i = 0 and check i<6;
Set j = 1 and check j <= i;
Print number n.
Then n++;
End

In this program, we are creating a right-angled triangle of numbers in increasing order. We are creating two loops, and 2^nd loop is executing according to the first loop, inside 2^nd loop printing the number row-wise i loop times.

JAVA

package programs;
public class pattern13 
{
    public static void main(String[] args) 
    {
        int n=1;
        for(int i=0;i<6;i++)
        {
             for(int j=1;j<i;j++)
             {
                 System.out.print(" "+n);
               n++;
             }
             System.out.println("");
        }
    }
}

Python

n = 5
k=1
for i in range(1,n):
    for j in range(0,i):
        print(k),
        k=k+1
    print("")

C program

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

C# program

using System;
public class Program
{
	public static void Main(string[] args)
    {
        int i, j, rows, k = 1; 
        Console.Write("\n\n");
        rows = 4;
        for (i = 1; i <= rows; i++)
        {
            for (j = 1; j <= i; j++)
                Console.Write("{0} ", k++);
            Console.Write("\n");
        }  
    }
}  

PHP program

<?php
$rows = 5;
$n = 1;
for($i = $rows; $i != 0; $i--)
{
    for($space = 0; $space < $rows - $i; ++$space)
    {
        echo $n;
          $n++;
    }
  echo "<br>";
}
?>
