      fun situations can arise when you write , instead of ; For those not in the know, in c++ the comma operator evaluates the left expression, discards the value, then evaluates the right expression and returns the value. if you now have a a situation like this

      int i = 0,
      printf("some message");
      

      i has a completely different value, since it actually uses the return value of printf instead
