This code appears to be written in Brainfuck, a minimalist programming language known for its simplicity and obfuscation. Here's a step-by-step explanation of what this code does:
Quick Brainfuck Primer
- Brainfuck uses a tape (array of memory cells) and a data pointer that starts at the first cell.
- Commands:
>
: Move the pointer to the right.<
: Move the pointer to the left.+
: Increment the value at the current memory cell.-
: Decrement the value at the current memory cell.[
: Begin a loop (execute only if the current memory cell is not 0).]
: End a loop (jump back to matching[
if the current memory cell is not 0)..
: Output the current memory cell as a character (ASCII value).,
: Input a character and store its ASCII value in the current memory cell (unused in this code).
Breaking Down the Code
-
>++
:- Move the pointer to the second cell (
>
). - Increment the second cell twice (
++
). - (Tape:
[0, 2, 0, ...]
).
- Move the pointer to the second cell (
-
<++++++++
:- Move back to the first cell (
<
). - Increment the first cell 8 times (
++++++++
). - (Tape:
[8, 2, 0, ...]
).
- Move back to the first cell (
-
[>---<+>]
:- This is a loop, which continues as long as the first cell is nonzero.
- Inside the loop:
- Move to the second cell (
>
), decrement it 3 times (---
). - Move back to the first cell (
<
) and increment it once (+
).
- Move to the second cell (
- Exit the loop when the first cell becomes 0.
- After the loop:
- The first cell will be 0.
- The second cell ends up being -22 (
2 * -11
).
- (Tape: `[0
