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

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

  1. >++:

    • Move the pointer to the second cell (>).
    • Increment the second cell twice (++).
    • (Tape: [0, 2, 0, ...]).
  2. <++++++++:

    • Move back to the first cell (<).
    • Increment the first cell 8 times (++++++++).
    • (Tape: [8, 2, 0, ...]).
  3. [>---<+>]:

    • 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 (+).
    • 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
