C: Good Habits re: Transitioning to C++

Question

I\'ve been learning C at Varsity for just shy of 2months now, and next year we\'ll be moving on to C++.

Are there any habits I should get into with my C programmin

Answer 1

Use structures and function pointers as much as possible to mimic the methods of the classes and the abstract methods.

For example, if you want to define a vehicle, and a car derived from vehicle using C, you would write (sorry, I won't check the code :-) ):

struct Vehicle
  {
  void (*checkFuel)(Vehicle*);
  void (*start)(Vehicle*);
  void (*move)(Vehicle*);
  void (*stop)(Vehicle*);
  }

void start1(Vehicle* v)
  {
  v->checkFuel(v);
  printf("START!");
  }

void start2(Vehicle* v)
  {
  v->checkFuel(v);
  printf("VROOOOMM!");
  }


struct Car
  {
  Vehicule base;
  int (*klaxon)(Car*);
  }

Vehicule* newVehicule()
 {
 Vehicule* v=(Vehicule*)malloc(sizeof(Vehicule));
 v->start= start1;
 v->move=
 (...)
 return v;
 }


Car* newCar()
 {
 Car* c=(Car*)malloc(sizeof(Car));
 Vehicule* v=(Vehicule*)c;
 v->start= start2;
 v->move=
 (...)
 c->kaxon=(...)
 return c;
 }
