Brainfuck Interpreter
INFORMATION
It is a plugin to interpret codes esoteric programming language BrainFuck in PAWN in a simple way.
NATIVES
To use it simply define the native and add the plugin to server.cfg.
EXAMPLES ..
Output: Hello World!
Possibly they knew that it is based on the ASCII table.

This is not absolute use (or maybe yes), can be used simply as a plugin to help you learn this language, possibly always is good to learn something new.

The language is based on a simple execution model consisting, besides the program, a vector of (at least) 30,000 bytes initialized to zero, a pointer to the vector (at the beginning of execution points to the first element of the vector) and two "streams" of bytes for input and output. |

native _BFInterpret(dest[], code[], len = sizeof(dest));
main()

The code "Hello World!" would be written in a single line: pawn Код:

pawn Код:
/* This program prints "Hello World!" and a newline to the screen, its
length is 106 active command characters [it is not the shortest.]
This loop is a "comment loop", it's a simple way of adding a comment
to a BF program such that you don't have to worry about any command
characters. Any ".", ",", "+", "-", "<" and ">" characters are simply
ignored, the "[" and "]" characters just have to be balanced.
