Brainfuck Demo

Intro

Brainfuck is an esoteric programming language with 8 very simple instructions created by Urban Müller. His aim was to create a Turing-complete language for which he can write the smallest compiler ever. His compiler was 240 bytes in size and later he had managed to bring it under 200 bytes.

The 8 operators that are used in the language are <>+-[],.. Even with these 8 operators a person is capable of writing almost any program that he can think of.

Below are the working of the above operators.

> = Increment the pointer.
< = Decrement the pointer.
+ = Increment the byte at the pointer.
- = Decrement 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.
, = Input a byte and store it in the byte at the pointer.
. = Output the byte at the pointer.
