# Program to Print Pattern 11

Program to Print Pattern 11 on fibonacci, factorial, prime, armstrong, swap, reverse, search, sort, stack, queue, array, linkedlist, tree, graph, pattern, string etc.

## Program to print the following pattern

A
B B
C C C
D D D D
E E E E E

### Algorithm

1. Start
2. Let i be an integer number.
3. Let j be an integer number.
4. Repeat step 5 to 7 until all value parsed.
5. Set i = 0 and check i<4;
6. Set j = 0 and check j <= i;
7. Print char(65+i).
8. End.

To accomplish this task, we need to use two loops, the first loop is responsible for printing the line breaks whereas the second loop is responsible for printing the alphabet.

### JAVA

```public class Pattern
{
public static void main(String[] args)
{
int n = 4;
for(int i = 0 ; i <= n ; i++)
{
for(int j = 0 ; j <= i ; j++)
{
System.out.print(" "+(char)(65 + i));
}
System.out.println("");
}
}
}
```

### Python

```k = 1
for i in range(1, 6):
for j in range(65, 65+i):
print(chr(64+i)),
print("")
```

### C program

```#include <stdio.h>
int main()
{
int n = 69;
for(int i = 65 ; i <= n ; i++)
{
for(int j = 65 ; j <= i ; j++)
{
printf("%c",i);
}
printf("\n");
}
return 0;
}
```

### 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((char)(row+64));
}
Console.WriteLine();
}
}
}
```

### PHP

```<?php
for (\$i = 65; \$i <= 69; \$i++)
{
for (\$j = 65; \$j <= \$i ; \$j++)
{
echo chr(\$i);
}
echo "</br>";
}
?>
```
