A simulation uses a room_loc to count windows in different rooms. What happens when the following code is executed?

 int kitchen = 0;
 int bedroom = 0;
 int* room_loc; // int POINTER room_loc;
 room_loc = &kitchen; ➊
 *room_loc = *room_loc + 1; ➋ // ACTUAL_VALUE(room_loc) = ACTUAL_VALUE(room_loc) + 1;
 room_loc = &bedroom; ➌
 *room_loc++; ➍
