How would I implement the constructor car in car.cpp?

#include "perf.hpp" #include "doors.hpp" class Car{ private: char* manufacturer; char* model; uint32_t zeroToSixtyNs; float headonDragCoeff; uint16_t horsepower; DoorKind backseatDoors; uint8_t seatCount; public: Car(); Car(char const* const manufacturerName, char const* const modelName, PerformanceStats perf, uint8_t numSeats, DoorKind backseatDoorDesign); Car(Car const& o); Car& operator=(Car const& o); ~Car(); char const* getManufacturer() const; char const* getModel() const; PerformanceStats getStats() const; uint8_t getSeatCount() const; DoorKind getBackseatDoors() const; void manufacturerChange(char const* const newManufacturer); void modelNameChange(char const* const newMode Name); void reevaluateStats (PerformanceStats newStats); void recountSeats(uint8_t newSeatCount); void reexamineDoors (DoorKind newDoorKind); }; #endif //CAR_HPP Car() o Default constructor. Initialize the pointer type variables with 'NULL' and the numerical variables with 'O'. 'DoorKind' variable is also initialized with 'None
