Simple Brainfuck Interpreter in C

This repository contains a simple Brainfuck interpreter written in C. The interpreter reads Brainfuck code from a file, parses it, and executes the commands in a memory buffer.

Features

• Supports all standard Brainfuck commands (>, <, +, -, ., ,, [, ]).
• Handles loops using [ and ] efficiently.
• Uses a fixed-size memory buffer of 30000 cells.

How does brainfuck works?

If you're here, you probably already know that, but here you go: The interpreter reads a file, then processes each character based on a instruction set:

• >: Move the memory pointer to the right.
• <: Move the memory pointer to the left.
• +: Increment the value at the current memory cell.
• -: Decrement the value at the current memory cell.
• .: Output the character at the current memory cell.
• ,: Read a character and store it at the current memory cell.
• [: Jump to the corresponding ] if the current memory cell value is 0.
• ]: Jump back to the corresponding [ if the current memory cell value is non-zero.

Compilation

To compile the program, use a C compiler like gcc:

gcc fuck.c -o interpreter

Running the Program

To run the interpreter, provide a brainfuck file as an argument:

./interpreter example.bf

Where example.bf is a file containing brainfuck code. There is a Hello World program in the repository as example.

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

Memory

The interpreter uses a static memory array of 30000 bytes. The memory pointer starts at the beginning of the array and can move left or right during execution.

Limitations

• Memory is fixed at 30000 cells.
• No input validation for brainfuck programs, so ensure valid syntax in your .bf files.
