Help with BF program
I found a BrainFuck Porgram and I wanted to know what it does.
Can anyone comment on what each step does?
I have no experience in this and someone with experience will probably recognize patterns they have seen earlier.
A big thanks to anyone who can explain to me.
To me it looks like a trolling program because of the consecutive <<>>

You may need to edit your post and take it out of the code tags, since the code tags swallowed that first set of "----"s
Try using output tags instead
As for the actual program, I can't help. I wouldn't touch this language with a 10-foot pole.

Removed the useless <>s.
It seems that this program reads a decimal number and then draws a triangle of that many zeros. I didn't run it, so I could be totally wrong though.

Nah, it's an esoteric language called "Brainfuck"
Basically, the language was designed to be damn near impossible to work with. (because the authors can) :P
