Hello World in Brainfuck

Introduction

In this tutorial, we will learn how to write a "Hello World" program in Brainfuck. Brainfuck is an esoteric programming language known for its minimalistic design and extremely minimal syntax. It consists of only eight commands, making it one of the simplest programming languages.

Prerequisites

To follow along with this tutorial, you need a basic understanding of programming concepts and familiarity with any programming language.

Brainfuck Basics

Brainfuck operates on an array of memory cells, each initially set to zero. It has a single pointer, usually denoted as ptr, which points to the current memory cell. The eight commands in Brainfuck are as follows:

• >: Increment the pointer (ptr) by one.
• <: Decrement the pointer (ptr) by one.
• +: Increment the value in the current memory cell (*ptr) by one.
• -: Decrement the value in the current memory cell (*ptr) by one.
• .: Output the ASCII value in the current memory cell (*ptr).
• ,: Accept one byte of input and store its value in the current memory cell (*ptr).
• [: If the value in the current memory cell (*ptr) is zero, jump forward to the corresponding ] command. Otherwise, move to the next command.
• ]: If the value in the current memory cell (*ptr) is nonzero, jump back to the corresponding [ command. Otherwise, move to the next command.

Writing Hello World in Brainfuck

To write a "Hello World" program in Brainfuck, we need to use the ASCII values of the characters. Here is the Brainfuck code that prints "Hello World":

++++++++++[>+++++++>++++++++++>+++>+<<<<-]>++.>+.+++++++..+++.>++.<<+++++++++++++++.>.+++.------.--------.

The above program increments and manipulates values in the memory cells to output the corresponding ASCII characters. Each character is output using the . command.

How to Run Brainfuck Code

To run Brainfuck code, you can use various Brainfuck interpreters available online or compile it into an executable using a Brainfuck compiler.

Let's try running the "Hello World" program using an online Brainfuck interpreter.

1. Open any online Brainfuck interpreter in your web browser.
2. Copy and paste the Brainfuck code into the interpreter.
3. Click the "Run" or "Execute" button to see the output.

Most interpreters provide an option to input custom values, but our "Hello World" program doesn't require any user input. It will directly print "Hello World" as output.

Conclusion

Congratulations! You have successfully written and executed a "Hello World" program in the Brainfuck programming language. Though Brainfuck may seem unconventional and confusing at first, it demonstrates the power of simplicity in programming languages. Now you can further explore Brainfuck by trying more complex programs or understanding its unique properties. Happy coding!
