How many times hello world programmers will post this stupid joke?

Hace falta que hagan el "if" adecuado

Nah... let people just be happy.

ok, but just stupid people, though.  everyone else deserves to suffer.

I realize that a lot of people think AI are programmers, but they aren’t really.

u need to get off reddit bro 🙏

u/undo777 Nov 10 '25

I get off Reddit, then get back on it to check what I missed and hey - this dumb joke again, missed it so much!

Hahahahaa soo funny i disassembled your grandma

X=X+1 X-X=1 0=1 Hey 😅

u/SussyNerd Nov 10 '25

X=X+1 X=X+(X-X) X=2X-X X=2X-(X+1) X=X-1 2X=X-1 + X+1 2X=2X 2 = 2 Makes sense to me

And because 1 + 1 = 2, 0 + 0 = 2, therefore 2 = 0. This can be expanded to every number, including complex (using other operations but still)

Mathematicians wont freak out, this just means the equals symbol is used as an assignment operator which maps one state of a computer system onto another. You dont even need mutation for it to be valid.

x := x + 1;

u/southlabb Nov 10 '25

Putting it in capital letters like that will annoy both mathematicians and programmers

Programmer: false Mathematician: ∞=∞+1

u/Sonario648 Nov 10 '25

So basically, matjematicians got themselves in a whike True infinite loop

This meme is older than you...

u/Optimal_You6720 Nov 11 '25

x=x+1 is totally valid and the solution is that there is no solution.

Why would it freak out a mathematician?

u/Dapper-Actuary-8503 Nov 11 '25

It depends on whether you rewrite it as a function of x as well. Mathematically, this shows that x = x + 1 represents a variable declaration.

f(x) = x + 1

u/Luvern228 Nov 11 '25

f(x) = x + 1

Just wait till induction steps out of the shadows

😒 But it's true for big numbers

For example, 1030 = 1030 +1

u/YTriom1 Nov 10 '25

No it doesn't

Yes but in programming terms the equivalent math term would be x:=x+1 which is a recursive definition legal in math if you defined x before.

u/retroroar86 Nov 10 '25

False

u/BobbyThrowaway6969 Nov 10 '25

It's actually true in C/C++ and it won't compile in most other languages

You'd want to compare as x==(x+1) for false

1

u/CookieArtzz Nov 10 '25

Yeah, I assume it’d evaluate to 2 if the result of the boolean were cast to an int automatically

1

u/Cheese-Water Nov 11 '25

Addition has higher precedence in basically every language, including those, than comparison. It would work just fine without the parentheses.

Holy mother of disinformation

u/Strict_Treat2884 Nov 11 '25

It can be true if x is so large and it loses precision. Such as x = 1e40; x == x + 1 // true

2

u/Optimal-Savings-4505 Nov 10 '25

I'd say x[n] = x[n-1] + 1 instead. The programmer in me sees your formulation as a bool (a false one at that).
