Start your new 2020 Bugatti Chiron!
Hit O to start your Engine!o

Car is now on! Safe driving!

So it isn't accepting any input after turning on the car.

_getch()?

Why are you using that?

It's grabbing the character value, then whatever that value is correspondences to a key. In this case, each of the cases denotes an arrow key and space bar.

When will startCar() return?
Kitsunetsuki (16)
probably never, I need help writing a function that subtracts gasoline while the car is on

int main(){
   while(true){
      userCar.update();
      //manage input
   }
}

void userCar::update(){
   if(this->is_on())
      gas -= 42;
   if(gas <= 0)
      this->turn_off();
}


also, avoid those magic numbers in your switch
