Array Getting Out Of Bound

11 days ago 18.8M views 0 shares

Einstein at 22: Revolutionizing physics with groundbreaking theories that changed humanity's understanding of the universe forever. You at 22: Still wondering why arr[arr.length] returns undefined instead of the last element. Spoiler alert: arrays are zero-indexed, so valid indices run from 0 to length-1. But hey, we've all been there—probably multiple times in the same debugging session. The contrast between buff Einstein and regular doge perfectly captures that feeling when you compare your accomplishments to historical geniuses. At least your IndexOutOfBoundsException won't cause a paradigm shift in theoretical physics... probably.

The Dreaded Edge Case Of Exactly 85 Percent

Someone forgot that = aren't mutually exclusive. When you need exactly 85% to pass, this brilliant logic says "sure, you both failed AND passed!" Congrats on achieving quantum superposition in your grading system. The real kicker? Both conditions evaluate to true when score equals 85, so you're printing both "FAILED" and "PASSED" to the console. Nothing screams "production-ready code" like Schrödinger's test result. Should've used an else-if or, you know, actually thought about boundary conditions for more than 3 seconds. Fun fact: This is why your code reviews exist. And why your QA team has trust issues.

Odd Building Permissions

Building number 477. You know, the one right before 478 and after 476. Except some architect with chmod privileges decided to skip straight to 477 like they were avoiding merge conflicts in real life. Either someone at city planning had a thing against even numbers, or they're running on the same logic as USB-C versioning. The building exists, the address exists, but somewhere a database admin is having an aneurysm trying to figure out why their sequential ID broke. Classic off-by-one error, except it's a whole building.

It Pays To Double Check They Say Part Two

Someone really, really wanted to make sure the player was dead before executing all those game-ending cleanup routines. Line 8 sets HP to -1, but then we get a beautiful cascade of nested if (HP==0) checks that will literally never execute. It's like building an entire mansion of death animations, sound effects, and instance destroys... and then locking the door and throwing away the key. The irony? They're checking for HP being exactly zero when they just set it to -1. So all those carefully crafted death sequences—stopping sounds, pausing boss music, spawning blood emitters, destroying boss items, playing death sounds, removing HP bars—are all sitting there in unreachable code purgatory. The player could be at -1 HP, technically dead, but the game's like "nah, you're good, keep playing." The "double check" here isn't defensive programming—it's defensive paranoia that accidentally created an immortality glitch. Should've been if (HP <= 0) or just removed that initial assignment. Classic GameMaker Studio moment right here.

Array Get Value At Negative Zero

Using dating as a teaching moment for zero-indexed arrays is definitely one way to cope with rejection. Sure, there won't be a second date, but hey, at least you managed to explain computer science fundamentals to someone who probably just wanted to grab coffee. The real tragedy here is that they still don't know about negative indexing in Python where you can access arrays from the end. Could've stretched that conversation for at least another awkward minute. Also, fun fact: in JavaScript, -0 and 0 are technically different values (thanks IEEE 754), but array[-0] still just gives you array[0] . Should've mentioned that on the date too. Really seal the deal.

A formatting bug caused a film review to display 1 star instead of the intended 0 stars. The correction was published on February 2, 2026—a date that hasn't happened yet. Someone pushed a datetime bug to production and nobody noticed until The Guardian had to explain why they're correcting reviews from the future. The Jira ticket for this probably has 47 comments, 3 sprint reassignments, and ends with "works on my machine." The real tragedy? The reviewer wanted to give it zero stars but the system said "nah, minimum is 1." Classic off-by-one error meets timezone chaos meets someone hardcoding dates. Beautiful disaster.

My Zeroth Meme Of 26

Nothing says "I've chosen chaos" quite like starting your year on Day 0 instead of Day 1. The zero-indexing gang is out here living their best life, celebrating New Year's on what normies call December 31st, while the one-indexing peasants are just... wrong. The skeleton villain dramatically retreating is basically every zero-indexer when confronted with the reality that the rest of humanity starts counting at 1. They'll be back next year though, still insisting that arrays should start at 0 and so should calendars, apparently. The commitment to the bit is honestly impressive.

It May Have Been Chucked Out The Window

You give the computer explicit instructions. The computer, being the literal-minded silicon brick it is, executes exactly what you typed—not what you meant, not what you needed, but what you actually told it to do . And now it's sitting there with that smug look, waiting for you to realize the bug isn't in the machine. The gap between "what I told it to do" and "what I wanted it to do" is where every developer's sanity goes to die. You spend three hours debugging only to discover you wrote i++ instead of j++ in a nested loop. The computer did its job flawlessly. You, however, did not. Welcome to programming, where the machine is always right and you're always wrong, but somehow it's still the computer's fault.

Congratulations, you've discovered Schrödinger's grade—simultaneously failing and passing until someone observes your code logic. The developer who wrote this clearly believes that 85 exists in some quantum superposition where it's both less than AND greater than or equal to 85. The real tragedy here isn't just the missing else statement—it's that both conditions will execute, concatenating "FAILED" and "PASSED" into the beautiful Frankenstein's monster that is "FAILEDPASSED". It's like the universe couldn't decide what you deserved, so it gave you both. Very existential. Pro tip: If your grading system outputs "FAILEDPASSED", you might want to reconsider your career choices. Or just learn about mutually exclusive conditions. Either works.

When You Post Increment Too Early

Someone updated that drowning counter with count++ instead of ++count and now zero people have drowned wearing lifejackets. Technically correct is the best kind of correct, right? The sign maker probably tested it once, saw it worked, shipped it to production, and went home early. Meanwhile, the lifejacket stat is sitting there at zero like "not my problem." Fun fact: The difference between i++ and ++i has caused more bugs than anyone wants to admit. Post-increment returns the value THEN increments it, while pre-increment does it the other way around. It's the programming equivalent of putting your shoes on before your socks—technically you did both things, just in the wrong order.

Kyoto Train Station Has Zero Indexed Platforms

Finally, a train station designed by programmers. While the rest of humanity insists on starting their platform numbers at 1 like absolute savages, Kyoto Train Station said "nah, we're doing this right" and went with Platform 0. Every developer who's ever had to explain why arrays start at 0 to a confused product manager just found their spiritual homeland. The Japanese really do think of everything—they've got bullet trains that arrive on the second, toilets that play music, and now platforms that actually make sense to anyone who's written a for loop. Meanwhile, the rest of the world's train stations are out here living in 1-indexed chaos like it's still the Middle Ages.

Zero-Indexed Relationship

Ah, the classic zero-indexed array defense. Technically correct but emotionally questionable. The guy told his girlfriend she's at index [1] in his array of interests, thinking he's being clever because that means she's his #2 priority after programming. But she's happy because she thinks 1 means first place. Nobody tell her that arrays start at 0 in most programming languages. That relationship is running on a critical misunderstanding that's somehow working. It's like production code that functions despite a lurking off-by-one error.
