I have a menu function like below and i add a pressEnter() function after each menu selected.   For menu other than findVehicle and parkVehicle, it is ok to for me to press enter and go to another line.  for that two function, after i need to press enter twice or i need to press a key and then an enter into go to new line.  Anything i need to in the function to avoid it?

 int Parking::run() {
 int selection = 0;
 bool complete = false;

 while (!isEmpty() && !complete) {
  parkStatus();
  parkingMenu.display();
  cin >> selection;
  if (selection == 1) {
   parkVehicle();
   pressEnter();
  }
  else if (selection == 2) {
   returnVehicle();
   pressEnter();
  }
  else if (selection == 3) {
   listParkedVehicle();
   pressEnter();
  } 
  else if (selection == 4) {
   findVehicle();
   pressEnter();
  }
  else if (selection == 5){
   complete = closeParking();
  }
  else if (selection == 6) {
   complete = exitParking();
  }
  
 }
 if (filename == nullptr) {
  return 1;
 }
 else {
  return 0;
 }
}

 void Parking::pressEnter() {
 cout << "Press <ENTER> to continue....";
 cin.get();
 cin.ignore();
