What's the most number of lines you have written for a project without testing and then had it run the first time? Also for context, what language did you use?

Feeling pretty good with my 200+ in C#.

I usually code in C/C++, and can't write more than 100 without an error during compile time/runtime.
My best streak was 2500+ in VisualBasic. Man, that language is so damn ez..

A pacman like clone, not sure how many lines, but after I had a window I stopped testing until I made movement, picking up dots etc. Only had to had ghosts in afterwards.

Python, around 400+ lines. Luckily I got just few warnings from flake8 about style but otherwise worked first try 😎

About 6.000 in Visual C++ utilizing com32. It wasn't possible to really test before that...

10 000 lines php code, had no internet and no local development enviroment. Just nano and the cli.

Had no internet, to that time i always developed directly on my server connected via ssh.

It just ran fine and i was so proud of myself.
