increment operator bug with globals?

[oddson]

int i;

void loop() {
  i=i++;
  Serial.println(i);
  delay(1000);
}

Doesn't increment.

That is correct. i++ is a post increment operator. I.e. it increments after the assignment. If you use ++i it should work.
Anyway, you probably meant i++, instead of the unusual i = i++; ?

Edit: actually it is undefined behaviour. (see https://stackoverflow.com/a/949443/1842762)

Right. Bone-head

I knew it works with locals but that's 'cause I use correctly there.

What would be the reasoning behind using i=i++ as opposed to just i++? For pointers I understand the difference, but I’m lost as far as regular variables go.

Bone-head is the reason... I should think a bit before posting
