What is Brainf**k?
Brainf**k is an *esoteric* programming language designed with one primary goal: to make your brain hurt! While it’s a fully functional programming language, capable of solving any problem that other Turing-complete languages can, it’s not meant for building practical software. Instead, it’s like a piece of art, meant to challenge your understanding of how programming languages should work.
Key Features:
- Minimalist Design: Created in 1993 by Urban Müller, a Swiss physics student, Brainf**k was made to have the *smallest possible compiler*. The original compiler is *less than 200 bytes*!
- Simple, Yet Powerful: Despite its simplicity, it is Turing-complete, meaning it can theoretically perform any computation, although not as easily as modern languages.
Brainf**k’s Working Structure
In Brainf**k, there are no variables, functions, or classes. The entire program operates on a *single array of 30,000 bytes*, where each value starts at zero. You control a pointer that moves over the array, and there are *only 8 commands* you can use:
>
: Move the pointer one cell to the right.<
: Move the pointer one cell to the left.+
: Increase the value in the current cell by 1.-
: Decrease the value in the current cell by 1..
: Output the value in the current cell as a character.,
: Input a character and store it in the current cell.[
: Start a loop, continuing while the current cell’s value is not zero.]
: End the loop started by the[
command.
Writing Code in Brainf**k
Let’s walk through how you would say “Hi Mom!” in Brainf**k.
Step-by-Step Example:
- Start with a 30,000-cell array, all initialized to 0.
- Use the commands to adjust the cell values to correspond to the ASCII characters for “Hi Mom!” (For example,
H
is 104,i
is 105, and so on). - To print
H
, you first move to a specific cell and increment its value until it reaches 104. Then you use the.
command to output the character. - You repeat this process for each letter in “Hi Mom!” by manually adjusting each cell’s value.
>++++++++[<+++++++++>-]<.>++++[<+++++++>-]<+.+++++++..+++.>>>++++++++[<+++++++>-]<.>>>++++++++++[<+++++++++++>-]<---.<<<<.+++.------.--------.>>>+.
Running Brainf**k Code
Once you’ve written your code, you can run it using an online Brainfk interpreter**. Just *copy-paste your code* into the interpreter, and voila! You’ve written a program in Brainf**k!
Why Learn Brainf**k?
While Brainf**k is not meant for developing apps or software, it offers a fun way to:
- Challenge your mind and rethink programming.
- Understand low-level memory manipulation, as Brainf**k works directly with memory cells.
- Experience the beauty of minimalism in programming.
Brainf**k may seem intimidating, but it’s a fantastic way to explore programming from a completely different perspective. By limiting yourself to just 8 commands, you’ll gain a deeper appreciation for more modern languages while also sharpening your logic and problem-solving skills.
So, give it a try and enjoy the challenge! You’ve just scratched the surface of the quirky world of Brainf**k!
