Classes and variables scope in C++

Question

class car {
    int speed; 
    double position;

    public:
       car(int v,double d);
       int getspeed();
};

int car::getspeed() {
return speed;
}

car::car(         


        

Answer 1

In your code:

car::car(int speed, double position){
   speed=speed;
   position=position;
}

you're just assigning each variable's value to itself. You can however do:

car::car(int speed, double position)
  :speed(speed)
  ,position(position)
{}

in addition to explicitly accessing the member variables via this->
