Have you ever heard about a programming language that's designed to be as minimalistic and mind-boggling as possible? Say hello to Brainfuck! This esoteric language is both fascinating and frustrating, making it a fun challenge for curious coders.

Purpose

The purpose of Brainfuck is not necessarily to facilitate efficient or practical programming; instead, it exists to push the boundaries of programming language design. With only eight commands and an extremely simple memory structure, Brainfuck forces developers to think in a completely different way compared to most traditional languages. It's an exercise in minimalism and creativity more than anything else.

Basic Commands

Brainfuck has only eight commands, which manipulate a memory array and a data pointer:

1. : Increases the data pointer.
2. : Decreases the data pointer.
3. : Increments the byte at the data pointer.
4. : Decrements the byte at the data pointer.
5. : Outputs the byte at the data pointer.
6. : Accepts one b

   Brainfuck Background

   According to Wikipedia, Brainfuck is an esoteric programming language created in 1992, and notable for its extreme minimalism. As people have implemented more and more ridiculous programs with the language, it has become relatively well-known over the years. Nowadays some see it as the ultimate coding challenge to create something useful in Brainfuck.

   At the core of the language is a more-than-compact instruction set, comprising of a whopping eight instructions. Brainfuck uses a machine model consisting of an infinite list of one-byte cells, an instruction pointer, and a cell pointer. The instructions can be used to interact with this environment:  and  move the cell pointer,  and  increment or decrement the value of the cell at the current pointer, and  and  denote a loop.

   A loop only starts when the value of the current cell is non-zero,
   

   Hello World in Brainfk

   18 May 2015

   This weekend, in a fit of boredom I thought I'd give Brainf**k a go. One of the most popular and recognized esoteric programming languages, I can't think of any real advantages that Brainf**k provides (If you can, let me know :) ). Richie Cotton has very kindly coded an interpreter for Brainf**k; you may find the code for the same here. I use his interpreter to write a HelloWorld program and a program that prints the integers 0 to 9.

   Here goes the HelloWorld code:

   And this beauty prints the integers 0 to 9:

   In keeping with the spirit of these languages, I haven't included any comments to help understand the code. If you need more understandable code, well-commented Brainf**k HelloWorld codes are present dime a dozen online. This Stackoverflow post gives a very engaging introduction to the language.
   The codes here are just something I threw together to see if I could get the hang of this language and are neither optimised for length nor efficiency. I would love to know how they can be improved on both counts, if you have any thoughts.

   The Art in Code

   Snippet source

   It doesn’t look like source code at first, but this snippet is actually valid code written in a language called Brainfuck.

   Brainfuck supports only 8 commands, each represented with a single character. These valid commands are: . Everything else is ignored.

   Brainfuck is considered an esoteric programming language meaning it has no practical purpose and is made for exploratory and research purposes, as a proof of concept or just for fun.

   You can run the snippet above by following this link.

   Explanation

   Brainfuck operates on top of a single “data” array and it can only manipulate a single element at a time, either changing its value or printing it out. and are used to move on to the next or previous element respectively, making Brainfuck function in a way that’s similar to a Turing machine.
