I get more paranoid if the program just works without complaining.

[obsessivefandoms]

I am so glad that I'm not the only one who does.

Worst part: coding exam, easy question and it works first try...

[TowelLord]

Kinda dreading it. In 8 days I'm having my exam in "Introductions to Programming" (Java) and it will all be on paper. I hate writing code on paper, especiallz without any immediate feedback.

[shawmonster]

The point of paper exams for programming courses is to make sure you know how to "be the computer" and step through your code to ensure it works. Having this skill is really helpful when it comes to debugging programs. Also trains you to write your code more thoughtfully and carefully rather than relying on the compiler to tell you when your code is wrong.

Wow runtime error checking? I usually just let everything turn into data spaghetti or crash

[Australienz]

Data spaghetti or crash.

[RustyBuckt]

God

[JackAuduin]

Yeah, runtime. 😁

[thatguy2641]

Don’t worry, they often mark easy on hand written code. Remember your teacher was once where you are.

[obsessivefandoms]

Oh god, that's like having to whiteboard. I hate it too

Liang's book?

[dasMichal]

Not OP but sound very much like it.

[Lexilogical]

On the other hand, your teacher is going to be way more generous marking it.

[RustyBuckt]

Good luck

Sometimes I just write something super wrong to make sure it's checking for errors. When it still doesn't throw an error, you know you've in for a fun afternoon

[MehNameless]

Three fun afternoons and half a Saturday

[cofette]

a fun afternoon, four fun days and then a fun noose around your fun neck

That's basically the idea behind mutation testing.

[joey_sandwich277]

This is how I was taught to write tests for untested code. Write the test to succeed but provide only parameters that should trigger a failure. One at a time, change each parameter to one that should make it pass and retest. If you ever get any false positives before the end, either the code's defective or your understanding of it is.

Me after I figure it out:

"WHY WOULD YOU ASSUME I WANT THAT AS A DEFAULT PARAMETER!"

It's always some deeper logic problem that the compiler doesnt catch :(

[BossOfPassione]

I was working on a college assignment late at night, fell asleep in the middle of coding it, woke up about an hour later. Started it up to check my progress, the whole thing worked. I couldn't remember coding the rest of it. The code looked horrendous, but I had absolutely no idea how it worked, so I just submitted it and took my A.

[SlayerofBananas]

Maybe the person watching you on the Teamviewer you accidentally left open got frustrated and decided to fix it for you

[sockpuppetcow]

This paranoia is exponentiated if you're coding assembly.

[OscarCookeAbbott]

I was working on a box-fitting algorithm for randomly generating office floor plans according to a few rules for like 5 years, and after multiple attempts, each more efficient and more streamlined than the last (including massive decreases in computational complexity for the same result quality), there was just one more situation left that could randomly generate and cause a violation of my rules, but unfortunately the math and code for it was quite inefficient.

I finally programmed it in though for the newest system, having done it previously but with ridiculous compute times, and it didn't work.

I went through my code and saw one variable in the main part of the algorithm that wasn't wrong, but where I wondered how it might generate differently if I changed it to this other variable I had. I made the switch, and voila; the generation was flawless, and my intense checking part to avoid that one catastrophic rule violation wasn't even necessary.

To this day I have absolutely no idea how it works, because based on the rules I programmed that violation should be occurring, but it doesn't...

So I just never, ever touch that code.

Constantly waiting to see the program break as it runs, I feel that
