Program to print the following pattern
Algorithm
In this program, we are creating a right-angled triangle of numbers in increasing order. We are creating two loops, and 2nd loop is executing according to the first loop, inside 2nd loop printing the number row-wise i loop times. 1 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>";
}
?>
