Read output and type input

See what your program prints, spot problems it reports, and answer it when it asks.

  1. Output, and answering back

    The console shows everything your program prints (stdout); a problem it reports appears in red (stderr). When the program asks for input (Python input(), Java Scanner), type your answer on the same line as the prompt and press Enter.

  2. Clear or copy the output

    From the console actions you can copy the whole transcript to paste elsewhere, or clear it to start fresh. Clearing only empties the view; your next run fills it again.
