C programming.

I need help changing the function vehicle* allocVehicle ( int t, int num, int row, int col ) in the program below to this description:

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)

For three types of vehicles (cars, trucks and SUVs), use the following enum construct to enforce that a vehicle must be one of three specific types:

enum VType { CAR, TRUCK, SUV }; 

/* Vehicle parking program */

//assignment2//

#include

#include

#include

#define CAR 1

#define TRUCK 2

#define SUV 3

#define CARFUEL 55

#define TRUCKFUEL 100

#define SUVFUEL 70

/* to store vehicle number, and its

row-col position in an array */
