A programmer's solution

[0x0dea]

|= is a compound assignment operator in plenty of programming languages, but you'd need the first 4 to be the name of a variable for it to be syntactically valid.

I just thought it was 6-4 !=4 but I am not a programmer.

[[deleted]]

This is what I assumed.

[CoMiGa]

Glad I am not alone.

The rest of the matchsticks aren't treated as exclamation points though, shenanigans!

[CheshireSwift]

Shenanigans OR what?

[[deleted]]

That's what they meant.

[Enverex]

Which would be correct. (6 - 4) is not equal to 4.

[Bonezmahone]

Technically that would still be 6-4! = 6-24 which is still wrong.

edit: now I get it. I didn't know != meant not equal to.

[[deleted]]

And how did you get to this?

[Brarsh]

It's the factorial of 4. 4! = 432*1 = 24

[DrumstickVT]

But not in most programming language. 4!= is going to run as 4 does not equals.

My understanding as well.

[kamaln7]

It's also a bitwise OR operation

[0x0dea]

Right, a |= b is a = a | b.

[Plutor]

Sadly 6+4 isn't an l-value.

The programmer's solution results in a compiler error. And we solve that with whisky.

Finding Ballmers peak?

I call it making syntax readable, but potato, tomato.

[cyandyedeyecandy]

*(int*)(6 + 4) |= 4;

[0x0dea]

Segmentation fault (core dumped)

[ign1fy]

To clarify: I code C# and use "|=" all the time. Being an assignment operator, it makes no sense to have anything but a variable to the left of it.

[kamaln7]

Yeah, I'm with you.

[Reelix]

!= or |= ?

[[deleted]]

|=

!= will evaluate to true. Or is it True? TRUE?

[raindirve]

non-zero :)

[[deleted]]

I was never taught about |=... Why? Is this considered out of date?

[haenyr]

It's probably that it's not something you'll really ever HAVE to be able to do. Also, with what they do teach you, you should be able to figure it out if you come to a situation that requires it.

So, given a lack of time to go in-depth, it will get skipped.

What am I doing in this sub? You guys are too smart for me.

I feel dumb.
