Brainfuck Interpreter

A slightly improved implementation of Brainfuck esoteric programming language.

Info

Brainfuck is the most famous esoteric programming language, and has inspired the creation of a host of other languages.

Brainfuck was invented by Urban Müller in 1993, in an attempt to make a language for which he could write the smallest possible compiler for the Amiga OS, version 2.0. He managed to write a 240-byte compiler. The language was inspired by False, which had a 1024-byte compiler. Müller chose to name the language brainfuck (with the initial letter in lower case, although it is now often capitalised).

Brainfuck Commands

Brainfuck operates on an array of memory cells, also referred to as the tape, each initially set to zero. There is a pointer, initially pointing to the first memory cell. The commands are:

• ">" Move the pointer to the right.
• "<" Move the pointer to the left.
• "+" Increment the memory cell under the pointer.
• "-" Decrement the memory cell under the pointer.
• "." Output the character signified by the cell at the pointer.
• "," Input a character and store it in the cell at the pointer.
• "[" Jump past the matching ] if the cell under the pointer is 0.
• "]" Jump back to the matching [ if the cell under the pointer is non-zero.

In this implementation I added 2 new commands (mainly to be used for debugging) :

• "#" Prints The Current Instruction.
• "$" Prints The Current Cell Address.

Features

• Written in C++.
• Turing-Trapit Language.
• Turing-Complete Language.
• Scripting Mode & Normal Mode.
• 10 commands instead of the original eight.

To Do

• Improve Memory Management Stuff
• Fix minor bugs

Sample Code

This program prints "Hello World!"
