And what about IntVars? can I use references two?for example: IntVar * get_IntVar(Space * h,IntVar * pos, IntVarArray & array) { IntVar * answer = new IntVar(h,1,1000); element(h, array, *pos, *answer); return answer; }
IntVar & get_IntVar(Space * h,IntVar & pos, IntVarArray & array) { IntVar answer(h,1,1000); element(h, array, pos, answer); return answer; } Are both "pointer safe"? I mean, is it necesary to allocate memory for IntVars using new, or when I create the IntVar object it allocates its own memory?
