# Program to Print Pattern 18

Program to Print Pattern 18 on fibonacci, factorial, prime, armstrong, swap, reverse, search, sort, stack, queue, array, linkedlist, tree, graph, pattern, string etc.

## Program to print the following pattern

1
1 2
1 2 3
1 2 3 4
1 2 3 4 5

### Algorithm

1. Start
2. Let i be an integer number.
3. Let j be an integer number.
4. Let n be a integer number and initialize by 7.
5. Repeat step 6 to 8 until all value parsed.
6. Set i = 0 and check i<n;
7. Set j = 1 and check j <= i;
8. Print number j+1.
9. End

### JAVA

```public class Pattern4
{
public static void main(String[] args)
{
int n = 5;
for(int i = 0 ; i <= n ; i++)
{
for(int j = 0 ; j < i ; j++)
{
System.out.print(j+1);
}
System.out.println("");
}
}
}
```

### Python

```lastNumber = 6
for row in range(1, lastNumber):
for column in range(1, row + 1):
print(column),
print("")
```

### C program

```#include <stdio.h>
int main()
{
int i,j,n;
n = 8;
for(i=1;i<6;i++)
{
for(j=1;j<=i;j++)
{
printf("%d",j);
}
printf("\n");
}
}
```

### C# program

```using System;
public class Program
{
public static void Main(string[] args)
{
for (int row = 1; row <= 5; ++row)
{
for (int col = 1; col <= row; ++col)
{
Console.Write(col);
}
Console.WriteLine();
}
}
}
```

### PHP program

```<?php
for (\$i = 1; \$i <= 5; \$i++)
{
for (\$j = 1; \$j <= \$i ; \$j++)
{
echo \$j;
}
echo "</br>";
}
?>
```
