C programming for a parking manager.

I need help fixing and finishing my program with the following function: (thanks for the help)

vehicle* allocVehicle(char* model, char* plate, VType type, double curFuel, double maxFuel ) - dynamically allocates space to store one vehicle record with the given model, plate, type, curFuel and maxFuel then initialize all its values sensibly (note: this function does not assign the vehicle a parking stall)

int deallocVehicle(vehicle* v) - deletes the given vehicle from the system and free up any allocated space that vehicles record was using

int assignStall(vehicle* v, int x, int y) - assigns the given vehicle the parking stall with the coor- dinates (x,y)

???? ng Manager is an application used to track the rovement of vehicles within a single parking garage You could imagine that this application was commissioned by a customer looking for a more efficient way to manage their parking garages. Below are some clarifying statements regarding Parking Manager to help you better understand the requirements All information stored in Parking Manager will be 'volatile" - meaning that all data stored is lost when the program terminates. By consequence, every time the program starts, the user begins with an empty parking garage. . For simplicity, the parking garage being modeled will be in the shape of a rectangle and stalls will be organized as a grid. You should use a 2D array to model the parking garage. . Parking Manager will only be responsible for managing one parking garage at a time. The intention is that each parking garage the customer owns will run a separate instance of Parking Manager. The following data is tracked for each vehicle entering the parking garage: vehicle model, licence plate, vehicle type, current fuel level in litres and maximum fuel level in litres . In addition to the data above, you will need a way to track the position of each vehicle within the garage. A vehicle can be one of three types: Car, Truck or SUV. . We can safely assume that every vehicle in the parking garage has been assigned its own parking stall Vehicles are added dynamically by the user - initially there will be no vehicles in the system The maximum number of vehicles which can be stored in the parking garage should be hard-coded in the source code, not determined by the user. When reporting on the current fuel level of a vehicle, you should report it as a percentage. This can be calculated from the current fuel level in litres and the maximun fuel level in litres ???? ng Manager is an application used to track the rovement of vehicles within a single parking garage You could imagine that this application was commissioned by a customer looking for a more efficient way to manage their parking garages.
