Automobile color, brand, model, and license plate number of the cars parked in the parking lot. Automobile objects are stable, meaning their attributes are specified at construction and they dont change thereafter. no default constructor. ClaimCheck a unique claim check number and the automobile associated with the claim. Students are issued a claim check when dropping off their vehicle, and redeem their vehicle with the claim check when picking up. Two claim checks are equal if they have equal claim check numbers. An automobile is associated with a claim check and a unique claim check number is generated at construction. There is no default constructor. Once a claim check is created it cannot be altered. The claim check number and the associated automobile may be queried from a claim check. ParkingLot Parking lots support dropping off and picking up automobiles. A student drops off an automobile and receives a claim check. A student provides a claim check and picks up an automobile. Traffic flow is enforced with one-way traffic spikes, so you cannot back up. Once you enter the aisle you must pull all the way through, if nobody is parked in front of you. When picking up, vehicles are removed one at a time from the front and added to the back until the desired car is found as illustrated below. If the claimed vehicle is not found in the parking lot, you can either throw an std::invalid_argument (strongly recommended but not required) or print an error message.
