  1. 0:55, on compiler options, try to pass the flag -O2 or -O3: it'll do that simplification for you. 3:15, the fastest approach here would be to have an enum like integers. This would dismiss any search. ie. C: enum completedStatuses { REFUND=0, CAPTURED, FAILED, CANCELED, MAX_STATUSES }; // All integers. if (labs (status) < completedStatuses.MAX_STATUSES) { // labs just to grant that status is not negative. // do some logic for completed orders... }
