Coding style

I used to write

While true
 Break;

But my teacher say it's bad and gives me a lower score for it
I mean wtf. Is there really a rules for coding style I mean as long as the result is fine it's no problem right?

Do you know that
while(x==1);
does the same and that
while(1){if(x==1)continue;else break;}
is BAD style and you should not program ever again?
