@Ganado That was the most amazing thing I’ve seen all day.
Ganado (6805)
lmao, with the first post now gone, it looks like I'm asking for help with assembly.
LunarLander (5)
That was also my first impression. What did the original post ask? And did you generate the assembly code from c++ code that would have been the answer to that question? The mangled names and the label names look like g++ assembly output to me.
Ganado (6805)
Yes it's g++ MinGW assembly. Probably won't build on linux, because of that SEH stuff. The original post asked (without showing any effort) for a program that did some really simple stuff (calculated the cost of buying tickets when there's a discount if you buy more than 5).

The joke was that they asked for a program, but didn't specify which language. The assembly is 100% a solution to the original question, and this was posted in the Lounge section and not the C++ sections. I even made sure I rounded the decimal places to the hundredths. But now I've over-explained the joke.

I like it. Maybe we should start giving them incoherent C++ solutions...

I suspected as such, not that I had a clue about the assembly. That is why I laughed at it.

But now I've over-explained the joke.

I still find it intensely hilarious. :)

Probably more so since the punchline was Lucy 'splained.

Before the question was deleted the OP said they had found the solution on their own and complained your reply was of no help. "...thanks for nothing..." was the response.
Ganado (6805)
Oh. That's hilarious. Guess they'll keep copying until it eventually bites them in the--.
LunarLander (5)
Thank you Ganado for the explanation.

@jonnin
Like an obfuscated C++ contest but for low-effort homework related questions?
jonnin (11429)
exactly!
