Brainfuck

Brainfuck is the coolest programming language ever.

http://esoteric.sange.fi/brainfuck/impl/interp/i.html

There are two global variables in every Brainfuck program, a pointer to a byte and an array of 30,000 or more bytes. All values are initialized to 0 in the array

> increments the pointer (goes forward 1 cell in the array)

< decrements the pointer (goes backward 1 cell in the array)

+ increments the value at the pointer

- decrements the value at the pointer

[ begins a loop whose entry condition is while(*ptr>0)

] ends the loop

, reads a byte from console into the value at the pointer

. writes the value at the pointer to the console

Anything other than these characters is considered comments and is ignored

print "Hello world!" is:

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

print "WATMM" is:

print "SEAN PLS" is:

QUITE GOOD

I've been doing some brainfuck programming. I've also made genetic algorithms that try to optimize brainfuck code size. They generate some weird ass code.

This one is generated from scratch by the genetic algorithm. It writes "Hi!"

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

If I remember correctly it took about 2000 generations with population of 100 brainfuck programs in each generation to generate this. It started with totally randomly generated code and used ASCII distance and program length as scoring methods to measure fitness.

how do you print "I hate women and darkies"?

The code is steganographically hidden in this picture

lol

Can it do anything besides print?

Me no understand this sheeit

No it can only traverse the 30KB+ array ("tape") by incrementing and decrementing the global pointer, and increment and decrement the values at the pointer.

I only program in LOLCODE:

HAI
CAN HAS STDIO?
IM IN YR LOOP UPPIN YR VAR TIL BOTH SAEM VAR AN 10
    VISIBLE SUM OF VAR AN 1
IM OUTTA YR LOOP
KTHXBYE
