A semicolon ends a statement, and semicolon is a statement on its own. One that does nothing. That's why you can write
int i;
for (i = 0; i ᐸ 3; i++);
to set i = 3. You can use that pattern to find something in an iterator, etc. But I would prefer
int i = 0;
while (i ᐸ 3) {
i++;
}
for readability.
Your less thans got HTML-escaped into < and I spent embarrassingly long trying to figure out what pointer magic you were demonstrating
Yeah, both Voyager and the normal lemmy web client escape the less-than sign. I tried it twice on both clients.
The loop will run to completion with no side effects. Unless it gets optimized away by the compiler or CPU.
Now slap some commas in there and you can have side effects in the loop header.
Guaranteed to confuse :)
It's actually ub, so it could also find the cure to cancer
Might help if you add some sample code
Pro tip: for(;;) takes less to type thann while(true)
My programs cause enough tears on their own without having to put them in the code itself.
#define EVER (;;)
As yes. Readability destroying anti-patterns. My old enemy
I still struggle to see how that's valid syntax
But it compiles.
Yes, I know. On the other hand, when you see people code-golfing C, this is on the light end of the spectrum
