Brainfuck

Hello Brainfuck 👋

Summary:

Brainfuck is a minimalist programming language, which only consists of only eight simple commands, a data pointer and an instruction pointe. And it is fully Turing complete.

Command	Function
>	Increment the pointer.
<	Decrement the pointer.
+	Increment the byte at the pointer.
-	Decrement the byte at the pointer.
.	Output the byte at the pointer in ASCII.
,	Input a byte and store it in the byte at the pointer.
[	Jump forward past the matching ] if the byte at the pointer is zero.
]	Jump backward to the matching [ unless the byte at the pointer is zero.

Principle:

You can use a 30000-byte array to play with. By default, the value of every byte in the array is 0. You'll be given a "pointer" that you can move around the array with. You can either increment or decrement the value of a byte using your pointer, output the value of it, or store a value in it...

Start:

The first step is to clone this repo and go to the root folder of it.

git clone https://github.com/yzhe819/Brainfuck.git

The second step is to compile, use gcc to compile a Brainfuck.exe.

gcc Brainfuck.c -o Brainfuck

Then, you can drag the Hello.BF file into this Brainfuck.exe.

Or run with the following command line below, it will read the entire file and print the output.

./Brainfuck ./Hello.BF

Finally, you can see the "Hello, World!" appear on your screen.

PS D:\project\Brainfuck> ./Brainfuck ./Hello.BF
Hello, World!

Code:

Arithmetic:

Subtraction

Source code:

The entire function can be implemented in 22 lines. The image below is a screenshot of the minimal version - Brainfuck.min.c. For a more detailed version see Brainfuck.c.

Feel free to modify the program and code and hope to have fun.
