C programming for a parking manager.

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

void printVehicle(vehicle* v) - prints all information about one vehicle void printAllVehicles() - prints all information for all vehicles in the system

void printGarageMap() - prints out a visual representation of the parking garage to the console
