Code: [Select]
while(oreo)
    oreo--;
Looking though this again, you could optimize:
Code: [Select]
while(oreo--);
I think the compiler does that for you.

In both cases the outcome is:
while:
branch if oreo is zero: endwhile
oreo --
branch to while
endwhile:


If we're talking about C/C++, I'm pretty sure they aren't equivalent: the first version only decrements oreo to 0, the second one to -1.

Most other languages too, but you can fix it:
Code: [Select]
while(--oreo);'
You're in trouble if you start with zero though.

Derp. Thanks for the fix. :)

Today I learnt something : life is made of algorithms. I discovered one today, being a student in my own appartment :

Code: [Select]
while(oreo)
    oreo--;

Did you discover things like this ?
Sorry for necro posting, but i felt like this needed a OOP update and a small reality check:  >:D :P
Code: [Select]
package Matrix.AIs.Matrefeytontias;

public class Matrefeytontias {

    private OreoBox oreoBox;
    public static OreoStore oreoStore;

    public static void main(String... args) {
        oreoStore = new OreoStore();
        Matrefeytontias matrefeytontias = new Matrefeytontias();
        matrefeytontias.live();
    }

    private void live() {
        while (oreoStore.hasOreos()) {
            buyOreos();
            while (oreoBox.hasOreos()) {
                oreoBox.eatOreos();
            }
        }
        //die
    }

    private void buyOreos() {
        oreoBox = oreoStore.buyBox();
    }

    static class OreoStore {

        int boxes;

        OreoStore() {
            boxes = 100;
        }

        OreoBox buyBox() {
            boxes--;
            return new OreoBox();
        }

        boolean hasOreos() {
            return boxes != 0;
        }
    }

    static class OreoBox {

        int numberOfOreos;

        OreoBox() {
            numberOfOreos = 50; //Correct me here please
        }

        void eatOreos() {
            numberOfOreos--;
        }

        boolean hasOreos() {
            return numberOfOreos != 0;
        }
    }
}

Hmm, seems like too much work to just eat Oreos.

That was sort of the point, to laugh at OOP :P
Also I am somewhat jealous that @Matrefeytontias has an Oreo store inside of him. :P  ;)
However I am a little freaked out that he has an Oreo box inside of him.   O.O  XD
