[Understanding question] Why does Alpaca append ".bin" to filenames instead of the actual extension?

[mags0ft]

Welcome, beloved Alpaca community.

I've been fiddling around with Alpaca's built-in code execution terminal, however I'm kinda confused. I believe this error is on my end though, because...

1. we know the terminal works, Jeffser tested it
2. there's certainly a reason it's been done the way it is

Look at this example:

I press the "play" button on the top right ...

... and the process fails to find the specific file:

(German for "No such file or directory")

I then looked at Alpaca's code for this very widget, and it seems like the wrong file extension is being used:

(file terminal_widget.py, lines 96-100)

The actual file is right there! See?

What am I missing here?

Thanks in advance.

C++ files get compiled into .bin

If the compiler is advised to write the binary into a .bin file as output, okay. But why doesn't it exist in the code runner directory then? What might've gone wrong here?
