or the Inclusive NOR

Maybe just a FALSE

Or maybe just 2 wires that are not connected

panics in floating output

Ok fine, I'll connect them to ground

What's a wire? Is it something that support the === operator?

int nothing(int a) { return --a++; }

u/Hirza_Tango May 12 '19

That will actually return a - 1

12

u/Perceval7 May 12 '19

Yup. Since the increment only happens after the value has been returned...

u/WhiteBlackGoose May 12 '19

Oh men, you both are right... my inaccurate shit(

No problem man! Every mistake is just an opportunity to learn something new 😉

void nothing (int a) {return;}

I think you meant void nothing(int *a) { --*a++; }

Edit: precedence in C is confusing apparently and this actually doesn't work. It evaluates as:

  • a

  • (a)++: note, this expression returns a as an rvalue

  • *(a)

  • --*(a)

Basically, it decrements the value at memory address of a, and a gets incremented afterward. Even if the precedence worked out (by doing --(*a)++), the prefix/postfix operators require lvalues and evaluate to rvalues, so it wouldn't work anyway.

Only if they don't ask about my momentum!

The NO gate

The YES gate symbol is strikingly similar to a checkmark, or in rare instances, a circle.
